Probably y = 8x. 56 = 8(7), so that works. Without more data, I couldn't say if it could be something else, so that's what I go with.
Answer:

Step-by-step explanation:
Given
V = πr²h ( isolate h by dividing both sides by πr² )
= h
When V = 36π , r = 3 , then
h = 
= 
= 4 cm
Answer:
see below
Step-by-step explanation:
2/3y + 15 = 9
Subtract 15 from each side
2/3y + 15-15 = 9-15
2/3y = -6
Multiply each side by 3/2 to isolate y
3/2 * 2/3y = -6 *3/2
y = -9
