Respuesta :
Two types of relationships between variables are direct and inverse variation. In general, direct variation suggests that two variables change in the same direction. As one variable increases, the other also increases, and as one decreases, the other also decreases.
Explanation :
When one variable decreases while the other variable increases, the relationship between them is inverse.
For example:
We know that pressure is defined as the force acting on an object per unit area.
Let the force applied on an object is F and its area is A. So, the pressure P can be written as :
[tex]P=\dfrac{F}{A}[/tex]
It is clear that when the area of the cross-section decreases, the pressure applied to it increases.
Hence, there exists an inverse relationship between the area and the pressure.
