Answer:

Step-by-step explanation:

We know that formula for average rate of change of a function from a to b is

Here f equals h and a =-3 b=5
h(a) = 
and
h(b) = 
h(b)-h(a) =
b-a = 5-(-3) =8
Hence average rate of change is

1.) 35,000+6,000+65+13
2.) 25,000+ 16,000+11,000+78

Answer:
<u>4 hours</u>
Step-by-step explanation:
Equations :
Larry : <u>y = 20x + 90</u>
Barry : <u>y = 30x + 50</u>
Equate both to find the number of hours at which they both charge the same :
- 20x + 90 = 30x + 50
- 30x - 20x = 90 - 50
- 10x = 40
- x = <u>4 hours</u>
