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

Answer: 2048
<u>Step-by-step explanation:</u>
h(x) = 4ˣ⁺² + 7
h(5) = 4⁵⁺² + 7
= 4⁷ + 7
h(-3) = 4⁻³⁺² + 7
= 4⁻¹ + 7
Average rate of change is the slope of the interval.

Answer:
the dryer costs $425
Step-by-step explanation:
x = washer
y = dryer
x + y = 803
x = y - 47
using the second equation a substitute in the first equation we get
y - 47 + y = 803
2y = 850
y = $425
FYI
x = y - 47 = 425 - 47 = $378
