How to solve inverse variation problems
WebMar 25, 2010 · Solve direct & inverse variation word problems. In this video the instructor teaches about direct and inverse variation. Two variables x and y are said to be in direct variation with each other if you can write them in the form y = K * x. The value of y varies directly corresponding to the value of x. Y is said to be directly proportional to x. WebThe equation of inverse variation is written as, This is the graph of y = { { - \,3} \over x} y = x−3 with the points from the table. Example 3: Given that y y varies inversely with x x. If x = …

WebThe simplest way I think of direct vs inverse variation is this way: in an equation, ask yourself what would the other variable do if one variable went up or down. If the other variable goes in the same direction, then the two variables vary directly. If they go in opposite directions, they vary inversely. WebOct 1, 2012 · The inverse variation relationship is: F = K d 2 Plug in the values F = 740 and d = 5.3 × 10 − 11: 740 = K (5.3 × 10 − 11) 2 Multiply both sides by (5.3 × 10 − 11) 2: K = 740 …
