Answer: b.
Step-by-step explanation:
Based on the information given, you can write the following expression:

Where k is the the constant of variation
If y=4/63 when x=3, then you can substitute these values into the expression and solve for k:

Substitute k into the expression. Then the equation is:

Substitute x=5 into the equation. Then, y is:

Answer:
20 > x > 10
Step-by-step explanation:
