What is the solution of the system of equations?
a.(5, -2, 7)
, 2, 7)
c.(5, 2, -7)
d. no solution

The answer to your question is: D. No solution

Step-by-step explanation:

See the picture

Δ = 0, it didn't finish because that means that it doesn't have solution

  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).
