10. To set up a wireless network for internet access at home, you must buy a network router for
$75. The fee for DSL service is $15 per month. If you have only $300 to spend on the setup
and service, for how many months can you get service? Let x represent the number of
months

15 months

Step-by-step explanation:

y represents the total cost in the equation. The words per month tells you that is where the x will go. 75 doesn't change you have to pay it no matter what so it will not have the x with it.

y = 15x + 75

To solve, plugin 300 for y, then solve for x.

300 = 15x + 75

300 - 75 = 15x + 75 - 75

225 = 15x

225/15 = 15x/15

x = 15 months

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10

804.75
