we know that
1) Lily swims a
-meter race
2) She swims the first half in
seconds
3) She swims the second half in
seconds
so
To find the total time to swim the whole race sum the time in the first half plus the time in second half

therefore
<u>the answer is</u>

To find the inverse of a relation, we switch the x and y values in each point.
So the inverse would be {(4, -3), (0, -1), (0, 6).
The glee club could have 6 members so the 48 classical CDs would be divided into 8 and the 42 show tunes could be divided into 7
1. added four to both sides
