Drag each expression to show whether it is equivalent to −1.3x−(−8.9x), −1.3x+(−8.9x), or neither.

Neither

Step-by-step explanation:

−1.3x−(−8.9x) = −1.3x + 8.9x = 7.6x

−1.3x+(−8.9x) = −1.3x −8.9x = -10.2x

Neither

  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).
