At the Piedmont Middle School baseball game last Friday, the Piedmont Ravens hit 3 times as many foul balls as the other team, the Rossville Crows. If the Ravens hit 8 more foul balls than the Crows, how many foul balls did the Ravens hit?

Step-by-step explanation:

Piedmont Middle School = 3x

Let the crows = x                     foul balls

x+ 8 = 3x                                    Subtract x from both sides

x-x + 8 = 3x - x

8 = 2x

x = 4

So the crows hit 4 foul balls

The ravens must have hit 12 foul balls.

They did hit 8 more than the crows did.

123

  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).
