A. f(x) = -(x + 1)? +7
B. f(x) = -(x+1)+ +9
C. f(x) = -(x+2)(x - 4)
D. f(x) = -(x-2)(x +4)

answer: y=4000x+14000

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
