Paul is comparing two high-speed internet service providers (isps) for his business. the graph represents the cost of each isp as a function of t, the duration in months of a service contract.
if c(t) = 180 + 10t represents isp a and c(t) = 25t represents isp b, how long would the service contracts need to be for the total costs to be the same?
6 months
8 months
10 months
12 months

The correct option is 4. The total costs will be the same at 12 months.

Step-by-step explanation:

The given equations represents the cost of each ISP as a function of t, the duration in months of a service contract.

ISP A:

ISP B:

Equate both the functions to find the time at which the total costs to be the same.

Subtract 10t from both the sides.

Divide both sides by 15.

The total costs will be the same at 12 months. Therefore the correct option is 4.

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
