Answer:
(3-1) + (1+3) = 4
Step-by-step explanation:
it is what i put there cause both letters you have to change it to a nuber thats makes the equation work up to 4
Answer:
89.51%
Step-by-step explanation:
Assuming given units are in cm
Tge rate of filling the cup is 70/2= 35 cm3/s
Volume of the cup is
and replacing r with 4 cm and h with 7 cm then the volume is equivalent to

Volume filled after 3 seconds will be 3*35=105 cm3
Percentage filled is 
Answer: y=3x-7
Step-by-step explanation:
First you have to get the equation in slope intercept form by moving x over then dividing by -1 because y cannot be negative
Then since you're trying to find the line that is parallel you use the same slope which is 3x
You then plug in the points which is 2=3(3) + b for you are trying to find teh y intercept
You then solve as normal and get y=3x-7
I am pretty sure this is correct
