Joint or Combined Variation

Videos, worksheets, games and acivities to help Algebra students learn about joint or combined variation.

Joint 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.
