What is an inverse proportion?
Two variables are said to be in inverse proportion if their product is a constant.So, if X and Y are in inverse proportion, thenXY = k or Y = k/X for some constant k.If you double X then Y is halved. If you decrease X by a factor of 3 then Y is trebled.A common example is Speed and Time for covering a fixed Distance.
What are the characteristics of inverse proportionality relationship?
If the product of two variables is equal to a constant, then they are inversely proportional. eg. If xy=c where c is a constant, then x and y are inversely proportional.
Is it always true for an inverse relation that the product of the two inversely related variables is constant?
It can't always be true. What if an inverse relationship crosses the origin, or one of the axes? In that case, at least one of the values (and therefore the product) will be zero.
What is a inverse variation function?
An inverse variation function describes a relationship between two variables where one variable increases as the other decreases, and their product remains constant. Mathematically, it can be expressed as ( y = \frac{k}{x} ), where ( k ) is a non-zero constant. This indicates that if ( x ) doubles, ( y ) will be halved, maintaining the constant product ( k ). Inverse variation is often seen in scenarios like physics, where certain quantities are inversely related, such as speed and time for a fixed distance.
When the product of two variables is a constant?
The Control Variable
What is the relationship between two variable if the product of the variables is constant?
inversely proportional or inverse proportion
What is the constant of portionality?
If two variables are directly proportional to one another then the constant of proportionality is the ratio of their values. If they are in inverse proportion then the constant of proportionality is the product of their values.

When the product of two variables is constant the variables are proportional to each other?
Yes. They are inversely proportional. The proportion y ∝ 1/x, means xy=K, where K is the constant.

A term used to describe the relationship between two variables whose product is constant?
The relationship between two variables whose ration is a constant value is a directly proportional relationship. An example of this is the ideal gas law, PV = nRT. Pressure and volume are directly proportional to the number of molecules of an ideal gas present ad the temperature.
What is the relationship between two variables if the product of the variables is constant?
Inversely proportional.
When the product of two variables is a constant?
The Control Variable
If values for x and y vary as an inverse proportion?
If values for x and y vary inversely, this means that as one value increases, the other value decreases and vice versa. This relationship can be represented by the equation xy = k, where k is a constant. This means that the product of x and y remains constant throughout the changes in their values.
Is a constant a number variable or the product of a number and one or more variables?
A constant is not a variable at all, and none of its factors was a variable. It is constant.
What happens to one variable when the other increases in an inverse relationship?
In an inverse relationship, when one variable increases, the other variable decreases. This means that as one variable gains value, the other loses value in a way that the product of the two variables remains constant. For example, if variable X increases, variable Y will decrease proportionately to maintain that constant relationship. This type of relationship is often represented mathematically as Y = k/X, where k is a constant.
