Booth Space
each day:$25

Electricity:$2

Which expression gives the total cost of
the day's rental if she used h hours of
electricity?

A. 25-2h
B. 25 + 2h
C.(25+2) x h
D. 25h+2

It is D

Step-by-step explanation:

I am not exactly sure how to explain but i'll try.

The 2 dollars is added to her price, so it is not A.

The 25 dollars is every day, so it is mutlipled by x. So its not B.

The 2 dollars is not everyday like the 25 dollars, so its not C b/c its not everyday.

-3

Step-by-step explanation:

I assume the graph is the one attached.

Comparing the points on each curve, f(x) is translated down 3 units and right 5 units to get g(x).  Therefore, the equation of g(x) is:

g(x) = (⅓)ˣ⁻⁵ − 3

So k = -3.
