Answer:
Assume x is directly proportional to y :

when y is 9, x is 2:
substitute to find value of k :

Therefore, equation is:

Answer:
h = V/lw
Step-by-step explanation:
We know the formula for the volume of a rectangular prism is V = lwh. We need to use this equation and solve for h by dividing lw on both sides.
V = lwh
V/lw = h
For number 5 you are just multiplying by 4.5
