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:
Set up the ratios as proportional fractions:
We can simplify the first fraction to make the problem easier. Both the numerator and denominator of the first fraction can be divided by 3:
Both fractions now have the same denominator. Since both fractions have to equal each other, the numerators will also be the same. Therefore, x = 4.
