Inverse variation formula refers to the relationship of two variables in which a variable increases in its value, the other variable decreases and vice-versa. In other words, the inverse variation is the mathematical expression of the relationship between two variables whose product is a constant.
In economics, the basic Law of Demand tells us that as the price for a particular good (or service) increases, the demand for that good (or service) will decrease. This is an inverse variation relationship. Suppose a new app is released for cell phones, and at a price of $$ \$4.99 $$ there are 3.2 million downloads each month.
There are many situations in our daily lives that involve inverse variation (indirect variation). For example, the number of days required to build a bridge is ...
For our example, the graph depicts the inverse variation. We say the water temperature varies inversely with the depth of the water because, as the depth ...
where k is referred to as the constant of proportionality. Direct variation word problems often contain verbiage such as: "varies inversely as"" varied inversely as" "inversely proporation to" Similar to direct variation word problems, those dealing with inverse variation may be solved using the following steps: 1) Recognizing the word problem consists of inverse variation as …

In notation, inverse variation is written as. Example: Suppose that y varies inversely as x and that y = 8 when x = 3. a) Form an equation connecting x and y. b) Calculate the value of y when x = 10. Solution: i.e. xy = k where k is a non-zero constant. a) Substitute x = 3 and y = 8 into the equation to obtain k. 3 × 8 = k ⇒ k = 24.
Since k is constant, we can find k given any point by multiplying the x-coordinate by the y-coordinate. For example, if y varies inversely as x, and x = 5 when ...
