# If y varies inversely as x and y = 320 when x = 25, how do you find y when x is 40?

To find y when x is 40, we can use the inverse variation formula: y = k/x. First, we need to find the constant of variation (k). We can do this by substituting the given values into the formula: 320 = k/25. Solving for k, we get k = 320 * 25 = 8000. Now we can use this value of k to find y when x is 40: y = 8000/40 = 200. Therefore, when x is 40, y is 200.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
