There are 22 problems in total involving direct and inverse variation, finding constants of variation, and solving for unknown variables. 3 @ Gina Wilson Things Solution: If the values of two quantities depend on each other in such a way that a change in one quantity results in corresponding change in other, therefore if the ratio between the two variables remains constant, it is said to be in direct variation. Then identify the equation that represents the relationship. docx), PDF File (. Direct Variation RECALL from Algebra 1: Direct, Inverse, Joint, and Combined Variation 9. 3 Inverse Proportion Two quantities may change in such a manner that if one quantity increases, the other quantity decreases and vice versa. Two variables are inversely proportional (also called varying inversely, in inverse variation, in inverse proportion) [2] if each of the variables is directly proportional to the multiplicative inverse (reciprocal) of the other, or equivalently if their product is a constant. The constant a is the constant of variation, and y is said to vary inversely with x. (3 30 -6) and (-3, -4) 17. For two quantities with inverse variation, as one quantity increases, the other quantity decreases. type of variation is inverse variation.
