Paul is comparing two high-speed Internet service providers (ISPs) for his business. The graph represents the cost of each ISP a

s a function of t, the duration in months of a service contract.
A coordinate grid showing Internet Service Provider Cost, with Service Contract in months along the horizontal axis, and Total Cost in dollars along the y-axis. Two lines are graphed. One line is labeled I S P A and passes through (0, 180) and (12, 300). The second line is labeled I S P B and passes through (0, 0) and (12, 300).

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?

Answer:

12 months

Step-by-step explanation:

Theres an awful amount of needless information to get through.

Only the last paragrph is needed.

C(t) = 180 + 10t

C(t) = 25t

Set the equations equal

25t = 180 + 10t

Subtract 10t from both sides

15t = 180

Divide both sides by 15

t = 12

Answer: x=3

Step-by-step explanation:

To solve this problem you must apply the proccedure shown  below:

- Multiply both sides of the equation by 3:

3(2x-3)=3(\frac{x^2}{3})\\6x-9=x^{2}

- Now you must make the equation equal to zero as following:

6x-9=x^{2}\\x^{2}-6x+9=0

- Factor it, as you can see below. Therefore, you obtain the following result:

(x-3)(x-3)=0\\(x-3)^2=0\\x=3
