Answer:
102
Step-by-step explanation:
Okay. I am guessing that you are asking for the amount of water poured per minute. The bathtub already holds 12 gallons and 32 - 12 is 20. The tub is full in 5 minutes. Let’s divide. 20/5 is 4. There are 4 gallons of water filled in the tub per minute.
Answer:
f(x)=-2x+9
f(4)+3=?
let x equal to 4
f(4)=-2(4)+8
f(4)=-8+9=+1
f(4)=1
then add 3 to f(4)
f(4)+3=1+3
f(4)+3=4
and he need f(4)+3 so the answer is
4
that's it
