Question

The variables x and y vary inversely with a constant of variation of 6.
Find y when x = 12.

Answer 1

To find y when x = 12, we can use the formula for inverse variation:

x * y = k

where k is the constant of variation, which is 6 in this case.

So, when x = 12:

12 * y = 6

Now, solve for y:

y = 6 / 12
y = 0.5

Therefore, when x = 12, y = 0.5.
