Al multiplicar 5a (2a +3b) se obtiene

10a + 15ab creo que sí? pero podría estar equivocada

(Perdona mi mal español,  estoy aprendiendo)

Step-by-step explanation:

5a x 2a = 10a

+

5a x 3b = 15ab

10a + 15ab

  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).

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
