Answer:
9.1 minutes.
Step-by-step explanation:
Let t represent time taken to fill the tank.
We have been given that a cold water faucet can fill a sink in 12 min, so the part of sink filed in 1 minute would be 
.
The hot-water faucet can fill it in 15 min, so the part of sink filed in 1 minute would be 
.
The drain can empty the sink in 25 min, so the part of drain emptied in 1 minute would be 
.
The part of 1 full tank filled in t minutes, when both faucets are on and the drain is open would be:
Make a common denominator:
Therefore, it will take 9.1 minutes to fill the sink.

Page 3
up 3, down 3, left 3, right 3
page 4
y = (x-2)^2 - 1
y = (x+1)^2 +3
The answer is going to be B. -34
