What is the result when the numbe 40 is decreased by 10%?

The answer is 36

Step-by-step explanation:

Decrease number by 40% of its value.

Percentage decrease = 40% × 10

New value =  36

40 - Percentage decrease =

40 - (10% × 40) remove the parentheses

40 - 10% × 40

(1 - 10%) × 40

(100% - 10%) × 40 = change 40 to 100% because 40 is a hundred percent of 10%

90% × 40

90 ÷ 100 × 40 =  36

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
