Answer:
13
Step-by-step explanation:
Since we want to find f(x) when x equals 10, we can substitute 10 in for x
f(x)=x/2 +8
f(10)=10/2+8
Divide 10 by 2
f(10)=5+8
Add 5 and 8
f(10)=13
So, f(x) when x=10 is 13
8.75 miles is 70%
12.5
1.25 is 10 percent
multiply that by 7
8.75 miles
what
your answer is 0 because it's a horizontal line
