Question

If y varies inversely with x and y = 14 when x = 3, what is y when x is 7?

Answer 1

Answer: When two variables vary inversely, the product of their values is constant. This means that x * y = k, where k is a constant.

We are given that y = 14 when x = 3, so we can use this information to find the value of k:

k = x * y = 3 * 14 = 42

Now that we know the value of k, we can use it to find the value of y when x = 7:

y = k / x = 42 / 7 = 6

So, y = 6 when x = 7.
