Answer:

the average rate of change for f(x) over the given interval is 2.

Step-by-step explanation:

The function f(x) = 2x + 2 has a straight line graph, and the slope of this line is always 2.  Thus, the average rate of change for f(x) over the given interval is also 2.

The ratio of wooden bats to metal bats in
lapo4ka [179]
<h3>Answer: 10 metal bats</h3>

"Ratio of wooden bats to metal bats is 2 to 1" basically means "there are twice as many wooden bats (compared to metal ones)". So if we had 3 metal bats, then we'd have 2*3 = 6 wooden bats. If we had 7 metal bats, then we have 14 wooden ones (because 2*7 = 14). And so on. The basic rule is to multiply the amount of metal bats by 2 to get the amount of wooden ones.

We can go in reverse to divide the amount of wooden bats to get the amount of metal ones. So 20/2 = 10 is the amount of metal bats.

------------------

A more formal approach is to use the proportion below to solve for x

20/x = 2/1

20*1 = x*2

20 = 2x

2x = 20

2x/2 = 20/2

x = 10

and we get the same answer.
