Direct, Inverse and Joint Variation Help. The relationship between two variables that vary directly is of the form y = kx . Note: x tripled, so y tripled. Note: k = y/x. When two variables vary directly, they appear to move in unison; i.e. if one doubles the other doubles, if one triples the other triples. The k factor is simply the relation, k ...

Joint and Inverse Variation. Whenever you hear that a relationship is joint between some variables and inverse with others, simply apply what you have learned above. Any variable that varies jointly or directly with another variable stays in the numerator and any variable that varies inversely stays in the denominator.

The general formula for inverse variation with a cube is y=kx3 y = k x 3 . The constant can be found by multiplying y y by the cube of x x . ... Now we use the ...

Direct, Inverse and Joint Variation. Solve the variation problems below. Note: Each problem has two (2) answers. Decimal answers should be rounded to the nearest hundredth. If y = kx, x and y vary directly. If y = k/x, x and y vary inversely. If z = kxy, z varies jointly with x and y.

k = 25 4. So the constant of proportionality becomes: k = 6.25. Now we have the variation equation as follows: y = kx2. y = 6.25x2. y = 6.25 ∗ 62. y = 225. As this is a direct relationship, you can also put the values in a direct variation calculator to find accurate results in seconds.

The calculator will find the constant of variation and other values for the direct, inverse (indirect), joint, and combined variation problems, with steps.
