Answer:
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 1, 1 ]
f(b) = f(1) = 3 ← value of y when x = 1
f(a) = f(- 1) = ← value of y when x = - 1
average rate of change = = =

Hi!
To solve this inequality, we have to isolate x on one side. Whatever we do to the equation we have to do it on both sides.
1.30x + 5.20 ≤ 18.20
Subtract 5.20 from both sides.
1.30x + 5.20 - 5.20 ≤ 18.20 - 5.20
1.30x ≤ 13
Divide by 1.30 on both sides.
1.30x/1.30 ≤ 13/1.30
x ≤ 10
