Answer:
We have that:

And we want to find the value of g(4)
Then we are evaluating the function g(x) in x = 4, this means that we need to locate all the "x" in g(x), and replace them by 4.
If we do that, we get:

Now we can just solve this to get:

Answer:
3/2 times as far
Step-by-step explanation:
Mai's distance divided by Noah's distance will give you your answer.
6.75 divided by 4.5 is 1.5 which is 3/2 as a decimal.
To solve this, you would divide the miles by the number of hours, 21 / 4
21 divided by 4 equals 5.25
5p-4p-8=-2+3
Combine like terms
p-8= 1
Add 8 to both sides to isolate p
p=9
Final answer: 1 solution only, p=9
