Solve the system of equations below.
y=x-1
x+y=3

x=2, y=1

Step-by-step explanation:

y=x-1

y=3-x

x-1=3-x

2x=4

x=2

  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).

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
