Answer:
B.
Step-by-step explanation:
The least amount of water in a pool is zero gallons.
It takes 16 minutes to reach zero gallons (the pool is empty).
The domain is from 0 to 16.
Answer: B.
Basically solve for y
minus 5x fromboth sides
-15y=-5x-60
divide both sides by -15
y=1/3x+4
We need to start from the innermost parenthesis and work our way out.
The first parenthesis is 
. These are not like terms because one involves a variable, while the other is a constant term. Two terms are summable if they involve the same power(s) of the same variable(s).
So, we can take one step outwards, and we arrive to the square brackets. We have
and 2z and -13z are like terms, so we can sum them:
Finally we arrive to the whole expression, which is
Because, again, 5z and 11z were like terms.
The answer is 49 because it is
