Answer:
f'(x)=-(x+42)/5
Step-by-step explanation:
Rewrite f(x) as y:
y=-5x-42
Flip x and y and solve for y:
x=-5y-42
x+42=-5y
(x+42)/-5=y
So the inverse function is f'(x)=-(x+42)/5 (note that f' means inverse)

Answer:
Y = 50
Step-by-step explanation:
Solve for Y:
Y - 9 = 41
Add 9 to both sides:
Y + (9 - 9) = 9 + 41
9 - 9 = 0:
Y = 41 + 9
41 + 9 = 50:
Answer: Y = 50
Is point B.
