# How do you write inverse variation equations given y=7 when x=4?

The inverse variation equation can be written as y = k/x, where k is a constant. To find the value of k, substitute the given values of x and y into the equation and solve for k. In this case, when x = 4 and y = 7, the equation becomes 7 = k/4. Multiply both sides of the equation by 4 to isolate k, which gives k = 28. Therefore, the inverse variation equation is y = 28/x.

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.
