网页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.
Joint or Combined Variation (video lessons, examples and …
网页Joint Variation or Combined Variation is when one quantity varies directly as the product of at least two other quantities. For example: y = kxz. y varies jointly as x and z, when there is some nonzero constant k. Joint Variation Examples. Example: Suppose y varies jointly as x and z. What is y when x = 2 and z = 3, if y = 20 when x = 4 and z = 3?

网页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. If x varies directly with y and inversely with z, we have \displaystyle x=\frac {ky} {z} x = zky. Notice that we only use one constant in a joint variation equation.
