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>

F(x)=IxI-5
when you shift it up, add the units to the end of y=IxI
when you shift it down, subtract the units to the end of y=IxI
The answer is B.
When you set up a ratio of all the corresponding sides, the ratios all equal 2:1
I think its A because the amount for one orange is .42
