If one wanted to solve the equation below using the quadratic formula, what would be the b value used to substitute into the quadratic equation.
3x 2 − 2 = - 5x
Answer:
b = 5
Step-by-step explanation:
All quadratic equations are formed in the format of \(a^{2}\) + bx + c = 0
Using this formula, we can re-arrange the equation to fit the given format.
\(3x^{2}\) - 2 = -5x
\(3x^{2}\) + 5x - 2 = 0
5 is plugged in for "b" in this equation, therefore b = 5.
Use the given information to find the measure.
Answer:
From the image, we can see that ∠AOC = ∠AOB + ∠BOC
We are given the following values:
∠AOC = 104
∠AOB = 7x + 30
∠BOC = 9x + 42
Plugging these values in the equation above:
∠AOC = ∠AOB + ∠BOC
104 = 7x + 30 + 9x + 42
104 = 16x + 72
16x = 32
x = 2
Now that we have the value of x, we can easily find the value of ∠BOC
We are given that:
∠BOC = 9x + 42
∠BOC = 9(2) + 42 (since x = 2)
∠BOC = 18 + 42
∠BOC = 60°
Therefore, ∠BOC is 60 degrees
Consider the enlargement of the rectangle.
A small rectangle with length of 4 and width of 2. A larger rectangle with length of 12 and width of 6.
Which proportional statements are true of the enlargement? Check all that apply.
The two given rectangles are proportional to each other since they have a width to length ratio of 2 and the area ratio between them is equal to 9.
How to determine the ratios related to two proportional rectangles
Two rectangles are proportional to each other when both have the same length to width ratio. The area ratio is defined by the following formula:
r' = (l' · h')/(l · h) (1)
Where:
l' - Length of the enlarged rectangle.l - Length of the original rectangle.h' - Length of the enlarge rectangle.h - Length of the original rectangle.Now we determine the length to width ratio of each rectangle:
Original rectangle
s = 4/2
s = 2
Enlarge rectangle
s' = 12/6
s' = 2
The two rectangles have the same length to width ratio.
And the area ratio is:
r' = (12 · 6)/(4 · 2)
r' = 72/8
r' = 9

Find the value of x.
Answer:
x = 82
Step-by-step explanation:
The sum of the interior angles of a polygon with n sides = (n-2) x 180°
This polygon has 7 sides so the sum of its interior angles
= (7-2) x 180°
= 5 x 180°
= 900°
Adding up the given angles we get
x + 160 + 2x + 125 + 110 + 112 + 147 = 900
3x + 654 = 900
3x = 900 - 654
3x = 246
x = 246/3 = 82
Answer:
x = 82
Step-by-step explanation:
Sum of interior angles of a polygon
\(S=(n-2) \times 180^{\circ}\)
where n is the number of sides.
The given polygon has 7 sides:
n = 7To find the value of x, substitute the sum of the interior angles and the found value of n into the formula and solve for x:
\(\implies x+160+2x+125+110+112+145=(7-2)\times 180\)
\(\implies x+2x+160+125+110+112+145=5\times 180\)
\(\implies 3x+654=900\)
\(\implies 3x+654-654=900-654\)
\(\implies 3x=246\)
\(\implies \dfrac{3x}{3}=\dfrac{246}{3}\)
\(\implies x=82\)
Therefore, the value of x is 82.
Carla asked students at a lunch table what their main course they liked. Out of these students, 28n liked pizza, 15 liked chicken nuggets, and 8 liked both. what is the probability that a randomly selected student will like pizza but not chicken nuggets?
The probability that a randomly selected student will like pizza but not chicken nuggets is (28n - 8)/(28n + 7), where 28n is the students who like pizza and 8 is students who like both pizza and chicken nuggets.
To find the probability that a randomly selected student will like pizza but not chicken nuggets.
Let P = the number of students who like pizza but not chicken nuggets
Then, P = the number of students who like pizza - the number of students who like both pizza and chicken nuggets
P = 28n - 8
So, the probability that a randomly selected student will like pizza but not chicken nuggets is:
P(Pizza but not nuggets) = P/(Total number of students)
We can find the total number of students who like either pizza or chicken nuggets by adding the number of students who like pizza and the number of students who like chicken nuggets, and then subtracting the number of students who like both:
Total number of students = 28n + 15 - 8 = 28n + 7
So, the probability that a randomly selected student will like pizza but not chicken nuggets is:
P(Pizza but not nuggets) = P/(Total number of students) = (28n - 8)/(28n + 7)

Resistance is a property of a material or circuit component that opposes the flow of electric current or the movement of an object through a fluid or gas. In the context of electric circuits, resistance is measured in units called ohms
what is falls freely means?
When an object is falling freely, it means that the only force acting on it is gravity, and there is no other force resisting its motion. In other words, the object is not being pushed or pulled by any other force apart from the force of gravity.
In the given question,
To solve the problem, we can set the formula for distance equal to the given height and solve for t:
s = 16t²
1060 = 16t²
Dividing both sides by 16 gives:

The 11% of respondents are identified as both Independent and swing voters which means that there is overlap between the two groups, i.e. they are not mutually exclusive.
Some voters may identify as Independent and also as swing voters, meaning they are not independent in terms of political affiliation, but are still considered swing voters because they are not firmly committed to one political party.

Select the correct answer. Which function represents the inverse function of the function f(x)=x^2 +5
Answer:
f^(-1)(x) = ±√(x - 5).
Step-by-step explanation:
Replace f(x) with y: y = x^2 + 5.
Swap the x and y variables: x = y^2 + 5.
Solve the equation for y. To do this, we'll rearrange the equation:
x - 5 = y^2.
Take the square root of both sides (considering both positive and negative square roots):
±√(x - 5) = y.
Swap y and x again to express the inverse function:
f^(-1)(x) = ±√(x - 5).

How to graph the equation on the coordinate plane.From the question, we have the following parameters that can be used in our computation:
g(x) = 2f(x + 1) - 2
Also, we have
f(x) = 2x
Recall that, we have
g(x) = 2f(x + 1) - 2
Using the above as a guide, we have the following:
f(x) = 2x
Add 1 to x
So, we have
f(x + 1) = 2(x + 1)
Subtract 2 from the function
So, we have
f(x + 1) - 2 = 2(x + 1) - 2
Substitute f(x + 1) - 2 = 2(x + 1) - 2 in g(x) = 2f(x + 1) - 2
g(x) = 2(x + 1) - 2

The point where the two lines intersect is the solution to the system of linear equations, which is: A. (300, 108).
How to Solve a System of Linear Equations?Given that:
y = total cost
x = miles
We are also given the system of linear equations that models the scenario given as:
y = 0.27x + 27 --> equation 1
y = 0.21x + 45 --> equation 2
To find the value of x, make both equations equal to each other and solve:
0.27x + 27 = 0.21x + 45
Combine like terms
0.27x - 0.21x = -27 + 45
0.06x = 18
Divide both sides by 0.06
0.06x/0.06 = 18/0.06
x = 300
To find the value of y, plug in the value of x into equation 1, and find y:
y = 0.27(300) + 27
y = 81 + 27
y = 108

If your base pay is 10000 your commission rate is 40% you sell 15 cars and you earn 40000 how much does each car cost
Answer: $4,000
Step-by-step explanation:
If the total earnings were $40,000 and the base pay was $10,000, then the commission earned would be $40,000 - $10,000 = $30,000.
Since the commission rate is 40%, we can set up the equation:
40% x Total Sales = Commission Earned
We know that the commission earned is $30,000, and we also know that 15 cars were sold. Therefore, we can solve for the average price of each car:
40% x Total Sales = Commission Earned
40% x (15 x Price per Car) = $30,000
6 x Price per Car = $30,000
Price per Car = $5,000
However, this is just the average price per car. Since the commission is based on the total sales, we need to calculate the actual commission earned on each car:
Commission per Car = 40% x Price per Car
Commission per Car = 40% x $5,000
Commission per Car = $2,000
Therefore, the total earnings of $40,000 divided by the number of cars sold (15) gives the amount earned per car:
Amount earned per Car = Total Earnings / Number of Cars Sold
Amount earned per Car = $40,000 / 15
Amount earned per Car = $4,000

Which graph represents the function f(x) = -|x| − 3?
A Reflection over the y-axis and a shift downwards by three units, which is consistent with the function f(x) = -|x| − 3.
The function f(x) = -|x| − 3 can be graphed by following these steps:
To begin, draw a regular x and y-axis and mark it off with an appropriate scale. Then, mark off the negative values on the y-axis and both negative and positive values on the x-axis. After that, we will begin graphing the function f(x) = -|x| − 3, which is a reflection of the absolute value of x over the y-axis and shifted three units down the y-axis. Since the function f(x) = -|x| − 3 is a reflection of the absolute value of x over the y-axis, the graph should be symmetrical. This means that each point to the left of the y-axis is a reflection of the point to the right of the y-axis. Then, we will plot the vertex (0, -3), which is three units down from the origin. Next, we can plot other points using a table of values. We can select values for x that are both negative and positive, such as -2, -1, 0, 1, and 2, and then evaluate them to find the corresponding y values. Then, plot these points on the graph. Finally, we connect the points with a smooth curve, which will form the graph of the function f(x) = -|x| − 3. The graph will be in the shape of a V that opens downwards.Therefore, the correct graph is an option (D). The graph of the option (D) shows a reflection over the y-axis and a shift downwards by three units, which is consistent with the function f(x) = -|x| − 3.

A school only provides bus service to students who live a distance greater

at the origin, and Michael lives at the closest point to the school on Maple Street
which can be represented by the line y = 4x + 6. If each unit on the coordinate
plane represents one mile, does Michael live far enough from the school for bus
service?
If each unit on the coordinate plane represents one mile, Michael does not live far enough from the school for bus service.
What is the slope-intercept form?Mathematically, the slope-intercept form of a line can be calculated by using this equation:
y = mx + c
Where:
m represents the slope.x and y represents the data points.c represents the y-intercept.Based on the information provided about Michael, we know that he is living at the closest point to the school (the origin) on Maple Street, which is represented by the line y = 4x + 6.
Therefore, slope (m) = 4
In Mathematics, a condition that must be met for two lines to be perpendicular is given by:
m₁ × m₂ = -1
4 × m₂ = -1
m₂ = -1/4
Since line 2 passes through the origin (0, 0), it can be modeled by this equation;
y = mx + c
y = -1/4(x) + 0
y = -x/4
Now, we can determine the coordinates for the location of Michael's house;
4x + 6 = -x/4
16x + 24 = -x
16x + x = 24
17x = 24
x = 24/17
x = 1.41
y = -x/4
y = -1.41/4
y = -0.35
Therefore, the coordinates of Michael's house is (1.41, -0.35).
For the distance from Michael's house to school, we have:
Distance = √[x² + y²]
Distance = √[1.41² + (-0.35)²]
Distance = √(1.9881 + 0.1225)
Distance = 1.45 mile.
In conclusion, Michael does not live far enough from the school for bus service because a distance of 1.45 mile is less than 3 miles.

2. Increasing the minimum wage has not traditionally caused massive unemployment though traditional economists have argued that it should. Why have changes to minimum wage not affected unemployment too much?
3. The US has one of the lowest federal minimum wages compared to other developed nations. Can you think of reasons why this might be?
4. The real minimum wage has fallen over time with the rise of inflation. This represents less purchasing power for minimum wage workers. Are you ok with that? Why or why not? How many people actually earn at or near minimum wage?
Despite traditional economic theory suggesting that an increase in the minimum wage should lead to unemployment, the actual impact on employment has been more nuanced. Empirical evidence suggests that moderate increases in the minimum wage have not led to massive job losses, but rather have resulted in small increases in labor costs that are offset by increased productivity and reduced employee turnover. Additionally, higher wages can increase consumer spending, leading to an increase in demand for goods and services, which can ultimately create more jobs.
There are several reasons why the federal minimum wage in the US is lower than in other developed countries. One reason is the political climate in the US, where there is often resistance to government intervention in the labor market. Additionally, many US states have their own minimum wage laws, which can be higher than the federal minimum wage. Finally, the US has a large low-skilled immigrant workforce, which can put downward pressure on wages.
I am not okay with the real minimum wage falling over time with the rise of inflation. Inflation erodes the purchasing power of workers, making it difficult for them to make ends meet. This can lead to increased financial hardship, which can have negative effects on individuals and families. Furthermore, the minimum wage was originally designed to ensure that workers earn a living wage, which is a basic necessity for a decent standard of living. As such, it is important that the minimum wage keep pace with inflation.
According to the Bureau of Labor Statistics, in 2021, about 1.9 million workers in the US earned at or below the federal minimum wage of $7.25 per hour. However, many more workers earn slightly above the minimum wage, and an increase in the minimum wage could potentially raise wages for those workers as well. Additionally, many states have higher minimum wage rates than the federal minimum wage, which means that the number of workers affected by changes to the minimum wage will vary depending on the state.
