Answer:

1. Direct Variation – is a relationship between two variables x & y such that the

ratio (or quotient) of y to x is a constant.

In symbols, y varies directly as x is written as y/x=k or y= kx where k≠0 is called

the constant of variation.

2. Inverse Variation – is a relationship between two variables x & y such that n

matter how the values of k, x, and y change, their product is a constant.

In symbols, y varies inversely as x is written as =

or k= xy where k≠0 is called

the constant of variation.

3. Joint Variation – is a variation where variable varies as the product of two or

more other variables.

In joint variation, z varies jointly as x and y. In symbols, we write, z = kxy or

=

where k≠0 is called the constant of variation.

4. Combined Variation – is a variation that involves both direct and inverse

variations.

The statement z varies directly as x and inversely as y means z =

or =

where k≠0 is called the constant of variation.
