Solve each system of equation using Subtitution
Y=x
Y=-x+2

(1, 1 )

Step-by-step explanation:

Given the 2 equations

y = x → (1)

y = - x + 2 → (2)

Substitute y = x into (2)

x = - x + 2 ( add x to both sides )

2x = 2 ( divide both sides by 2 )

x = 1

Substitute x = 1 into either of the 2 equations for y

Substituting x = 1 in (1)

y = 1

Solution is (1, 1 )

  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).
