A computer store charges $45 for materials and $50 an hour for service to install two new programs and a connection. The cost C(h) is a function of the number of hours h it takes
to do the job. Graph the function C(h) - 45 + 50h.
a) How much will a 3-hour installation cost?
b) Find h when C(h) = 395. Explain what the answer means.
c) Find C(5) Explain what the answer means

answer: i think it is (1,-2)

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
