Does anyone know 3x-13=4x+7

x=-20

Step-by-step explanation:

3x-13=4x+7

3x-13+13 = 4x+7+13

3x=4x+20

subtract from both sides

3x-4x = 4x+20-4x

combine like turms

-x=20

divide both sides of the equation by the same term

-x =20

-x/-1 = 20/-1

x=-20

I hope that this helped

  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).
