How do you write an inverse variation equations given y = 5 when x = 2?

Answer 1

xy=10

Inverse variation equation between two variables signifies that xy remaining any constant number, x would be inversely proportional to y and vice-versa.

In the present case that constant number is 10. The inverse variation equation would be xy=10

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 = 2 and y = 5, the equation becomes 5 = k/2. Solving for k, we multiply both sides of the equation by 2, resulting in k = 10. Therefore, the inverse variation equation is y = 10/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.
