Simplify the following expression by adding like terms: 17x + 3y - 4x + 4y 10x + 10y
13x + 7y
4x + 2y
None of the above

21x+7y (None of the above)

Explanation to the

13x + 7y

Step-by-step explanation:

You add the 17x + -4x. so you subtract 4 from 17 because a positive plus a negative means subtraction. you then add 3y + 4y, and 3 plus 4 equals 7 :)

  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).

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,
