Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.
<h3>Variation</h3>
y = k × x
where,
k = constant of proportionality
y = -40
x = -5
y = k × x
-40 = k × -5
-40 = -5k
k = -40/-5
k = 8
when,
y = 8 and x = 2.5
y = k × x
8 = k × 2.5
8 = 2.5k
k = 8/2.5
k = 3.2
when,
y = 5 and x = 4
y = k × x
5 = k × 4
5 = 4k
k = 5/4
k = 1.25

4% divided by 100 is 0.04 which is the decimal then u take 56 divided by 0.04 which is 1400 so 4% of 1400 is 56 apples
Answer:
When Finding the Y-Intercept from a Graph and Table, you are searching for the point of intersection between the equation and the y-axis. When finding the Y-Intercept from a Graph, you should find where the line from the equation crosses the y-axis. The point where the equation crosses the y-axis is the Y-Intercept.

Answer:
x = 30
y = 54
Step-by-step explanation:
You want the solution to the system of equations ...
- 2x +12 +2y = 180
- 4x +y +6 = 180
<h3>Solution</h3>
Divide the first equation by 2 and subtract the result from the second equation.
(4x +y +6) -(2x +12 +2y)/2 = (180) -(180)/2
3x = 90 . . . . . . . simplify
x = 30 . . . . . . . . divide by 3
4(30) +y +6 = 180 . . . . substitute into the second equation
y = 180 -126 = 54
The values of x and y are ...
x = 30
y = 54

<em>Additional comment</em>
A suitable graphing calculator can find the solution using the equations "as is."
