In 48 days, they would have consumed 108 gallons, and have 22 left, so yeah. 48 days
A + B + C = 180
<span>C = 180 - A - B </span>
Subtract 6 from the x value in the first one, and remember that slope intercept form is mx+b
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)
