Answer:
a) 72
b) $259.2
Step-by-step explanation:
A- The bus travels 40 miles on 8 gallons of gasoline. The bus is traveling 360 miles in total.
360/40= 9
9*8= 72
B- $3.60 per gallon and 72 gallons in total.
3.60*72=259.2
$259.2

Answer:
Step-by-step explanation:
You have the domain. It is given as -1≤x≤1
Now all you have to do is figure out the range which is the y value. At first glance I think it might be 3, but that does not look very logical. I'll post this much of it now and be back in under an hour with a more complete answer.
Of course! How silly of me. There is a minimum of y = 1 in the range which comes from x = 0
I've included a graph so you can see how this all works.
So the range = 1 ≤ y ≤ 3
24 and 28
These are the only two numbers (other than 20 itself) that have a factor of 4. And if you were to find all of their common factors, 4 would be the greatest!
