Well they give you the equation and they want you to solve for time given that you know the amount of water in the tank. They tell you T=274 and that
T=450-8m so using the value T=274 in the equation to the left gives you:
274=450-8m subtract 450 from both sides
-176=-8m divide both sides by -8
22=m
So 22 minutes have passed when there is 274L remaining...
Answer: (3,4)
Each input can only have one output for a function
The other pairs give a different output for the input so that would make it a relation not a function.
Umm I didn't get a domain.... No solutions were found...
(Use order of operations(PEMDAS))
14(4)+28-12(5)
56+28-60
84-60
24
solution=24
1. it helps you by being the first number you use to divide
2 you can multiply the quotient and dividend to check your answer so you can check if the quotient is right, to see if its right it should equal the divisor.
