Answer:
y=4x
Step-by-step explanation:
In a proportional relationship, two values always have the same ratio to each other. This means that when we look at the equation of a line, y=mx+b, where m=slope and b=how much more plus the slope y is, there cannot be a "b" value.
An example of this is:
If the slope is 3,
y=3x
If x=2, y=6
If x=5, y=15
We can see that for every pair of coordinates, the ratio (5) between x and y remain the same.
y cannot have anything added to i (ex: y=3x+1), otherwise the ratio would change.
Ex:
If the equation is y=3x+1,
If x=1, y=4
If x=2, y=7
We can see that the ratios between the two numbers (1/4, 2/7) are not the same.
In this problem, the only equation without "b" is y=4x. Therefore, the answer is y=4x.
y=4x

Answer: y = -5.5x +18
Step-by-step explanation: -11/2 = 5.5
Answer: y= -11/2x + 7
Step-by-step explanation:
(2,7) and (4,-4)
Do \(\frac{y^{2} - y^1}{x^2-x^1} \\\) so it should look like this \(\frac{-4-7}{4-2} =\frac{-\\11}{2}\)
\(\frac{-11}{2}\) is your slope
Then you need to find your "b" term.
\(-4=\frac{-11}{2} (2) +b\)
Multiply -11/2 by 2 and add 11 to both sides
Then do -4 + 11 which equals 7
So 7 is your b term
So your answer is y= -11/2 + 7

A tart contains either 3 white, or 4 red, or 5 black cherries. A tray of 20 tarts contains 89 cherries. How many red cherries are on the tray if it contains 3 tarts with white cherries?
Answers
- x be the number of tarts with white cherries
- y be the number of tarts with red cherries
- z be the number of tarts with black cherries
From the problem, we know that each tart can only have one type of cherry. So we can set up the following system of equations:
x + y + z = 20 (the total number of tarts is 20)
3x + 4y + 5z = 89 (the total number of cherries is 89)
We also know from the problem that each tart with white cherries contains 3 cherries. So the total number of white cherries is 3x. We are looking for the number of red cherries, which is 4y.
To solve for y, we can use substitution. We can rearrange the first equation to get:
z = 20 - x - y
Then we substitute this expression for z in the second equation:
3x + 4y + 5(20 - x - y) = 89
Simplifying this equation, we get:
2x - y = -3
Now we can solve for y by isolating it on one side of the equation:
y = 2x + 3
We know that each tart with white cherries contains 3 cherries, so the total number of white cherries is 3x. We also know that each tart with black cherries contains 5 cherries, so the total number of black cherries is 5z. So we can rewrite the equation for the total number of cherries as:
3x + 4y + 5(20 - x - y) = 89
Simplifying this equation, we get:
2x - y = -3
Now we can solve for y by isolating it on one side of the equation:
y = 2x + 3
We know that each tart with white cherries contains 3 cherries, so the total number of white cherries is 3x. We also know that each tart with black cherries contains 5 cherries, so the total number of black cherries is 5z. So we can rewrite the equation for the total number of cherries as:
3x + 4y + 5(20 - x - y) = 89
Simplifying this equation, we get:

To design a spinner with the given probabilities, we can use the following sectors:
A sector covering 60 degrees for the number 1, with probability 1/6.
A sector covering 120 degrees for the number 3, with probability 1/3.
A sector covering 180 degrees for the number 7, with probability 1/2.
A sector covering 180 degrees for the odd numbers (1 and 3), with probability 1.
To create the spinner, draw a circle and divide it into four equal sectors. Color one sector red for the number 1, color two adjacent sectors green for the number 3, color one remaining sector blue for the number 7. Finally, color half of the blue sector green to represent the odd numbers.
The resulting spinner will have the desired probabilities: P(1) = 1/6, P(3) = 1/3, P(7) = 1/2, P(odd number) = 1.

Two business partners decided to borrow $30,000 start-up money for their business. One borrowed a certain amount at a 16.5% interest rate and the other one borrowed the rest of the money at a 12.5% interest rate. How much money did each business partner borrow if the total interest amount at the end of the year was $4150?
Answers
Answer:
Step-by-step explanation:
Let's assume the first business partner borrowed x dollars and the second partner borrowed (30000 - x) dollars.
The interest earned by the first partner at a rate of 16.5% is (x * 0.165), and the interest earned by the second partner at a rate of 12.5% is ((30000 - x) * 0.125).
According to the given information, the total interest earned by both partners is $4150. So, we can write the equation:
(x * 0.165) + ((30000 - x) * 0.125) = 4150
Now, let's solve this equation to find the values of x.
0.165x + 0.125(30000 - x) = 4150
0.165x + 3750 - 0.125x = 4150
0.04x = 400
x = 400 / 0.04
x = 10000
Therefore, the first business partner borrowed $10,000 at a 16.5% interest rate, and the second partner borrowed (30000 - 10000) = $20,000 at a 12.5% interest rate.
Let's call the amount borrowed by the business partner at 16.5% "x" and the amount borrowed by the other business partner "y".
We know that the total amount borrowed is $30,000, so:
x + y = $30,000
We also know that the interest earned by the first business partner is 16.5% of x, and the interest earned by the second business partner is 12.5% of y.
So the total interest earned for the year is:
0.165x + 0.125y = $4150
We now have two equations with two unknowns, which we can solve for x and y.
First, let's isolate one of the variables in the first equation:
x = $30,000 - y
Now we can substitute this expression for x into the second equation:
0.165($30,000 - y) + 0.125y = $4150
0.165($30,000 - y) + 0.125y = $4150
$4,950 - 0.165y + 0.125y = $4150
Combine like terms:
-0.04y = $4150 - $4,950
-0.04y = -$800
Divide both sides by -0.04 to isolate y:
y = -$800 / -0.04
y = $20,000
Now that we have the value of y, we can substitute it back into the first equation to find x:
x + $20,000 = $30,000
x = $30,000 - $20,000
x = $10,000
So, the amount borrowed by the first business partner is $10,000, and the amount borrowed by the second business partner is $20,000.

2. Pencils measuring less than 5 inches: 3 + 2 + 3 = 8 inches in total.
3. False. To determine if more than half of the pencils are 6 inches or shorter, we need to find the total number of pencils and calculate how many of them are 6 inches or shorter.
Total number of pencils = 4 + 3 + 2 + 3 + 7 + 8 = 27
Number of pencils that are 6 inches or shorter = 4 + 3 + 2 + 3 = 12
To find out if more than half of the pencils are 6 inches or shorter, we need to divide the number of pencils that are 6 inches or shorter by the total number of pencils and multiply by 100%:
12/27 x 100% = 44.44%
Since 44.44% is less than 50%, the statement is false.
4. There are three pencils that measure more than 5.5 inches but less than 7.5 inches: 6, 6, and 7. Therefore, the answer is 3 pencils.

Answer:

What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
Suppose the number of eggs eaten by hot dogs be x.
Then, the total number of eggs is x + 2.
As per the question the inequality can be written as follows,
18 < x + 2 < 25
Subtract 2 from all parts of the inequality to get,
18 - 2 < x < 25 - 2
=> 16 < x < 23
Hence, the inequality that best describes the number of eggs hot dogs eat per week is given as 16 < x < 23.
