# If y varies inversely as x, and y=10 as x=7, how do you find y for the x-value of 10?

To find y for the x-value of 10, we can use the inverse variation equation. Inverse variation is represented by the equation y = k/x, where k is the constant of variation.

To find the value of k, we can use the given information that y = 10 when x = 7. Plugging these values into the equation, we get 10 = k/7.

To solve for k, we can multiply both sides of the equation by 7, resulting in 70 = k.

Now that we have the value of k, we can substitute it back into the inverse variation equation to find y for the x-value of 10.

Plugging in x = 10 and k = 70, we get y = 70/10. Simplifying this, we find that y = 7.

Therefore, when x = 10, y will be equal to 7.

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.
