F(x) = 8x
y = 8x
x = 8y
x/8 = y
y = x/8
f^-1(x) = x/8
The answer is A-g(x)=-x^2-4
Answer:
x=0 and y=−8
Step-by-step explanation:
4x+4y=−32
4x−4y=32
Add these equations to eliminate y:
8x=0
Then solve 8x=0 for x:
8x=0
(Divide both sides by 8 to get x by itself)
x=0
Now we plug x back in to solve for y.
4x+4y=−32
Substitute 0 for x
(4)(0)+4y=−32
4y=−32 (Simplify both sides of the equation)
(Divide both sides by 4 to get y by itself)
y=−8
