Answer:
Answer C
Step-by-step explanation:
If x varies inversely as y, it means that their product remains constant.
We can set up the equation:
x × y = k
where, k → constant of variation.
Given that when x is 12, y is 3, we can substitute these values into the equation:
12 × 3 = k
36 = k
Now we can use this value of k to find the value of y when x is 4:
4 × y = 36
y = 36 / 4
y = 9
Therefore, when x is 4, y is 9.
