All three points displayed are on the line. Find an equation relating x and y.
(6,9)
(3,3)

Answer: She mixed up the slope and y-intercept when she wrote the equation in step 3.

Step-by- explanation:

Hope this helps :)

Brooke did a mistake in step 3 Brooke's error was he interchanged the slope and y-intercept.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\(\rm m =\dfrac{y_2-y_1}{x_2-x_1}\\\)

We have:

Brooke found the equation of the line passing through the points (–7, 25) and (–4, 13).

\(\rm m =\dfrac{13-25}{-4+7}\\\)

m = -12/3

m = -4

y = -4x + b

Plug x = -7, y = 25

25 = -4(-7) + b

b = 25 - 28

b = -3

y = -4x - 3

Thus, Brooke did a mistake in step 3 Brooke's error was he interchanged the slope and y-intercept.

Step-by-step explanation:

24 - (3 * 2)

Answer:

x+y = 36

x-y = 10

Add these two equations to get

2x = 46

x = 23

Sub x=23 into either equation, I like the first.

23 + y = 36

y = 13

23,13 are the pair.

The correct set of possible results would be (0, 1, 0, 0), (1, 2, 1, 0) and (1, 2, 0, 1).

Your approach seems to be correct, but there seems to be a minor mistake in your final list of possible solutions. Let's go through the steps to clarify.

Given the initial conditions z=t=0, you obtained a partial solution (0,1,0,0).

Next, you solved the homogeneous equations for z=1 and t=0, which resulted in a solution (1,1,1,0).

Similarly, solving the homogeneous equations for z=0 and t=1 gives another solution (1,1,0,1).

To find the general solution, you combine the partial solution with the solutions obtained in the previous step, using parameters a and b.

(0,1,0,0) + a(1,1,1,0) + b(1,1,0,1)

Expanding this expression, you get:

(0+a+b, 1+a+b, 0+a, 0+b)

Simplifying, you obtain the following set of solutions:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Therefore, the correct set of possible results would be:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Note that (0, 1, 1, 1) is not a valid solution in this case, as it does not satisfy the initial condition z = 0.

Step-by-step explanation:

5% of 70,000 is 3,500 (70,000 x 0.05 = 3,500)

That means she is earning at least $3,500 a month from interest.

$3,500 is plenty to cover the monthly payment of $280.

You know what, I think Jessica should get a brand new car instead.

Yes, her monthly interest will cover the cost of the down payment and Jessica should get a brand-new car instead.

If n is the number of times the interest is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

\(a = p(1 + \dfrac{r}{n})^{nt}\)

We have given that Jessica has $70,000 in the bank and is earning 5% compounded monthly.

And the down payment is $500 and the monthly payments are $280

5% of 70,000 = 3,500

70,000 x 0.05 = 3,500

That means that she is earning at least $3,500 per month from interest.

$3,500 is plenty of amounts to cover the monthly payment of $280.

Therefore, Yes her monthly interest will cover the cost of the down payment and Jessica should get a brand-new car instead.

Step-by-step explanation:

Elida's lowest score is 6.

What is a range?

The difference between a collection of numbers' highest and lowest values is known as the range. Subtract the distribution's lowest number from its greatest number to determine it.

Here, we have

Large value = 18, range = 12

To find the lowest score, we apply the formula

Range  =  Large value - Small value

L  =  18, R  =  12

12  =  18 - Small value

Small value  =  18-12

Small value  =  6

Hence, Elida's lowest score is 6.

Answer:

4 ^2 −20 +2 5

Step-by-step explanation:

I did the math

The possible y-coordinate are 6 and -2. Therefore, the possible coordinates of point B are (2, 6) and (2, -2).
The mistake your friend made was assuming that the distance between two points is only dependent on the y-coordinate. This is not true, as the distance between two points is determined by both the x-coordinate and y-coordinate.

Therefore, there are multiple possible coordinates for point B that could have a distance of 5 units from point A.


To find the possible coordinates of point B, we need to use the distance formula:

Distance = √((x2 - x1)² + (y2 - y1)²)

Given that point A has coordinates (-1, 2) and the x-coordinate of point B is 2, we have:

5 = √((2 - (-1))² + (y - 2)²)

Solving for y:

25 = (3)² + (y - 2)²
25 = 9 + (y - 2)²
16 = (y - 2)²

Now, taking the square root of both sides:

±4 = y - 2

So, the possible y-coordinates are 6 and -2. Therefore, the possible coordinates of point B are (2, 6) and (2, -2).

Your friend made a mistake by saying the coordinates of point B could be (3, 5). This is incorrect because the x-coordinate of point B should be 2, not 3. Additionally, the y-coordinate of point B should be either 6 or -2, not 5.

We have that the sides of a right triangle receive different names depending on the angle we are going to analyze.

The opposite side of the right triangle is the hypotenuse:

And depending on the angle we are going to analyze, one side is that opposite to it and the other side is the adjacent:

We know by the Pythagorean Theorem that:

opposite² + adjacent² = hypotenuse²

In this case

hypotenuse = 20

adjacent = 16

opposite BC

Then

opposite² + adjacent² = hypotenuse²

↓

BC² + 16² = 20²

↓

BC² = 20² - 16²

BC² = 144 = 12²

In this case:

angle = A

opposite side = 12

hypotenuse = 20

Then,

If we simplify it, we have:

We have that the Cosine Formula is:

In this case:

angle = A

adjacent side = 16

hypotenuse = 20

A bar chart is a graph that shows the differences in frequencies or percentages among categories of a nominal or an ordinal variable.

A bar chart is a commonly used graphical representation to display the distribution of data in different categories. It is particularly useful when working with nominal or ordinal variables, where the categories are distinct and unordered or have a specific order.

In a bar chart, each category is represented by a rectangular bar whose length corresponds to the frequency or percentage associated with that category. The height of the bar represents the magnitude or count of the variable in each category, allowing for easy visual comparison between the categories.

The bars in a bar chart can be arranged horizontally or vertically, depending on the preference or nature of the data. The chart may also include labels or annotations to indicate the category names or additional information.

By examining the lengths or heights of the bars in a bar chart, it becomes easy to identify the categories with the highest or lowest frequencies or percentages, as well as to compare the relative magnitudes among the different categories. This graphical representation aids in visualizing and interpreting the distribution of a nominal or an ordinal variable effectively.

The statement that shows equivalent measurements is "52 meters = 520 decimeters." Option C.

To determine the equivalent measurements, we need to understand the relationship between different metric units.

In the metric system, each unit is related to others by factors of 10, where prefixes indicate the magnitude. For example, "deci-" represents one-tenth (1/10), "centi-" represents one-hundredth (1/100), and "kilo-" represents one thousand (1,000).

Let's analyze each statement:

5.2 meters = 0.52 centimeters: This statement is incorrect. One meter is equal to 100 centimeters, so 5.2 meters would be equal to 520 centimeters, not 0.52 centimeters.

5.2 meters = 52 decameters: This statement is incorrect. "Deca-" represents ten, so 52 decameters would be equal to 520 meters, not 5.2 meters.

52 meters = 520 decimeters: This statement is correct. "Deci-" represents one-tenth, so 520 decimeters is equal to 52 meters.

5.2 meters = 5,200 kilometers: This statement is incorrect. "Kilo-" represents one thousand, so 5.2 kilometers would be equal to 5,200 meters, not 5.2 meters.
