Answer:

He gets 42 visitors 4 weeks after starting to build his website.

He gets 10 new visitors per week.

Explanation:

Equation for the number of visitors:

The equation for the number of visitors Timmy's new website receives after t weeks is:


v(t) = 10t + b

In which b is the number of visitors rightly after he starts.

Timmy is building a new website. Right after he starts, he has 2 visitors.

This means that
b = 2, so:


v(t) = 10t + 2

How many visitors does he get 4 weeks after starting to build his website?

This is v(4). So


v(4) = 10(4) + 2 = 40 + 2 = 42

He gets 42 visitors 4 weeks after starting to build his website.

How any new visitors does he get per week?

After 0 weeks:


v(0) = 10(0) + 2 = 0 + 2 = 2

After 1 week:


v(1) = 10(1) + 2 = 10 + 2 = 12

2 weeks:

After 2 week:


v(2) = 10(2) + 2 = 20 + 2 = 22

22 - 12 = 12 - 2 = 10

He gets 10 new visitors per week.
