Answer

mr. nigma is solving the system of equations 4x-3y = 9 and 2x+6y=5. which system of equations has the same solution as the system mr. nigma is solving?

a. {4x-3y=9

-15y=-1

b. {4x-3y=9

9y=19

c. {2x+6y=5

6x=23

d. {2x+6y=5

10x=23

  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).
