Translate the sentenfe into an inequality.

twice the difference of a number and 5 is less than or equal to 18.

use the variable w for the unknown number.

w ≤ 4

Step-by-step explanation:

Variable = w

Difference of the number and 5 = w - 5

twice the difference = 2(w - 5)

less than or equal to 18

2(w - 5) ≤ 18

2w - 10 ≤ 18

2w ≤ 8

w ≤ 4

  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).
