Mrs. Higgins graphed the function f(x)= -2(7/10)x
She asked her students to transform f(x) 9 spaces down and 4 spaces to the right.
Shari’s answer was f(x)= -2(7/10)x+4 -9
Drew’s answer was f(x)= -2(7/10)x-4 -9
Joel’s answer was f(x)= -2(7/10)x+9 +4
Chris’s answer was f(x)= -2(7/10)x-9 +4
Which student was correct?

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

it would open into a square depending on the type of envelope i’m not sure about the second part

the answer is about 24 dollars
