# Assume y varies inversely as x, how do you write the equation given y=12 when x=-9?

The equation can be written as y = k/x, where k is the constant of variation. To find the value of k, substitute the given values of y and x into the equation and solve for k. In this case, when y = 12 and x = -9, the equation becomes 12 = k/(-9). Solving for k, we get k = -108. Therefore, the equation is y = -108/x.

The equation for inverse variation is y = k/x, where k is the constant of variation. To find the value of k, plug in the given values for y and x and solve for k. Then, use the value of k to write the equation.

Given: y = 12 when x = -9

Using the given values: 12 = k / -9

Solving for k: k = 12 * -9 k = -108

Therefore, the equation for the inverse variation is: y = -108 / 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.
