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)

We have an equation: ?/100= 48/60
Cross multiply:
60*?= 48*100
⇒ ?= 48*100/60= 80
48 is 80% of 60~
Answer: 2(3c^2+2)
Step-by-step explanation:
Get rid of the parentheses : 5c^2-2c+4 + c^2+2c
Combine any like terms: 5c^2-2c+4 + c^2+2c = 6c^2-2c+4 +2c
Combine like terms: 6c^2-2c+4 +2c = 6c^2+4
Then just factor by grouping: (5c^2-2c+4) + (c^2+2c) = <u>2(3c^2+2)</u>
