Answer:
The one on the bottom CANNOT be represented by the equation.
Step-by-step explanation:
For the equation in the problem there has to be a 4x, meaning the cost per case multiplied times the about of them (x). Then there has to be a +7 somewhere in the equation for shipping. The two on the top fit both of those descriptions.

Answer:
y =4
Step-by-step explanation:
8(y – 2) = 4y
Distribute
8y -16 =4y
Subtract 8y from each side
8y-8y -16 = 4y -8y
-16 = -4y
Divide each side by -4
-16/-4 = -4y/-4
4 = y
Answer:
A'(5,3)
Step-by-step explanation:
First, you must understand that A(5,3) is the pre-image and that A' is what we are looking for which is the image.
With that in mind, you translate the preimage by adding or subtracting from the x and y values.
(x+4, y-3)
To find the x value of the pre-image, you will add 4 to the preimages' x value
Pre-image: A(1,6)
To find the y value, you subtract the preimages' y value by 3.
