2x - 6 = 3x + 1 -x - 7

infinitely many solutions

Step-by-step explanation:

Simplify 3x + 1 - x - 7 and you'd get 2x-6 = 2x-6

Since that statment is true, it's infinitely many solutions

  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).
