8/5 - 12x

Step-by-step explanation:

-4(-2/5+3x)

multiply everything by -4

-4(-2/5) + -4(3x)

-4(-2/5) - 12x

8/5 - 12x

Why is 8/5 postive? The two negatives canceled out

D

Step-by-step explanation:

A and C are both incorrect for the same reason: They both believe that 12x is positive.

So that leaves B and D. B is incorrect because it leaves 8/5 as negative which is incorrect: 2 minuses multiplied make a plus.

So how about D? It is the correct answer.

  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).
