Answer:
f^-1(x) = -1/8x +1/4
Step-by-step explanation:
To find the inverse of a function
Exchange x and y and then solve for y
y =-8x+2
Exchange x and y
x = -8y+2
Now solve for y
Subtract 2 from each side
x-2 = -8y+2-2
x-2 = -8y
Divide by -8
(x-2)/-8 = -8y/-8
Distribute
-1/8x +1/4 = y
f^-1(x) = -1/8x +1/4
I think it’s 2 5/9. You might want someone to double check it, though.
Answer: 120+20x=280
Step-by-step explanation:
280-120=160
160/20=8
The correct answer is the last one, 120+20x=280
They are parallel since x and y are bottom and top
