### Which is the best definition of joint variation?

## Which is the best definition of joint variation?

Joint variation is a variation in which the quotient of a variable and the product of two variables is a constant. It occurs when a variable varies directly or inversely with multiple variables.

## What is joint variation give an example?

Joint variation is a variation where a quantity varies directly as the product of two or more other quantities. For example, the area of a rectangle varies whenever its length or its width varies. We say that A ∝ lw, where A is the area, l is the length and w is the width.

**How do you determine joint variation?**

Equation for a joint variation is X = KYZ where K is constant. One variable quantity is said to vary jointly as a number of other variable quantities, when it varies directly as their product.

**What is the difference between combined and joint variation?**

Joint variation is just like direct variation, but it involves two or more variables: y=k(xz). Combined variation is a combination of direct and inverse variation: y=kx/z.

### What does a joint variation look like?

Joint variation occurs when a variable varies directly or inversely with multiple variables. For instance, if x varies directly with both y and z , we have x=kyz x = k y z . If x varies directly with y and inversely with z , we have x=kyz x = k y z .

### What is the difference between joint and combined variation?

In Algebra, sometimes we have functions that vary in more than one element. When this happens, we say that the functions have joint variation or combined variation. Joint variation is direct variation to more than one variable (for example, d = (r)(t)). With combined variation, we have both direct variation and indirect variation.

**Which equation’s represent joint variations?**

Joint variation problems are solved using the equation y = kxz. When dealing with word problems, you should consider using variables other than x, y, and z, you should use variables that are relevant to the problem being solved.

**What is joint variation in math?**

Joint variation is a more complex relationship between three variables, where one variable varies directly as one variable and inversely as another. The equations expressing combined variation take the form x = ky/z.

## What is an example of combined variation?

Combined variation is a variation where a quantity depends on two (or more) other quantities, and varies directly with some of them and varies inversely with others. Example 1: A quantity varies inversely as two or more other quantities. The figure below shows a rectangular solid with a fixed volume.
