The definition is pretty simple:

So, we only have to sum the expressions:

Mavis drives = 634 miles.
Mavis visits her grandmother 4 times.
That means, she drives 634 miles each time when she visits her mother.
One time round trip Mavis's house to her gramdmother in philadelphia = 634 miles.
If she visited 4 times, we can multiply one round trip distance by 4 or we can just add that distance four times.
Let us try it by multiplying 4 by 634 .
If we multiply 4 by 634, we get 2536.
Therefore, 2536 miles Mavis drives if she visits her grandmother 4 times.
Answer:
x- intercept is 6 y- intercept is -18
Step-by-step explanation:
Just use the graph, this graph is hard to get the answer but you just have to estimate.
3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
False if y=f(x) then x= inverse of f(x) or f^-1(x)
