8 0

Answer:

b=1

Step-by-step explanation:

Given -> -40-8b=-6(1+7b)

Distributive Property -> -40-8b=-6-42b

Add 40 to both sides -> -8b=34-42b

Add 42b to both sides -> 34b=34

Divide both sides by 34 -> b=1

What is the average rate of change for this function for the interval x=2 to x=4?
andrezito [222]

Answer:

12

Step-by-step explanation:

The average rate of change in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ 2, 4 ]

f(b) = f)4) = 32 ← from table

f(a) = f(2) = 8 ← from table

Then average rate of change is

\frac{32-8}{4-2} = \frac{24}{2} = 12
