Direct inverse or joint variation

• How do you solve inverse variation problems?

  Inverse variation problems are modeled using rational equations in the form of y . Example 3. Solve the variation problem. Given: y varies inversely as x , and y 95 when x 3 . Find y when x 15 . 3 Use the inverse variation model y k . Substitute the x given values for x and y , and solve for k .

• How do you solve a joint variation problem?

  Joint variation problems are modeled using equations in the form of y kxz . Example 5. Solve the variation problem. Given: y varies jointly as the square of x and z, and y 1334 when x 8 and z 3 .

• What if quantities vary inversely?

  When quantities vary inversely, we say that “ y varies inversely as x ” or that “ y varies inversely in proportion to x ”. Inverse variation problems are modeled using rational equations in the form of y . Example 3. Solve the variation problem. Given: y varies inversely as x , and y 95 when x 3 .

• How do you solve a direct variation problem?

  When quantities vary directly, we say that “ y varies directly as x ” or that “ y varies directly in proportion to x ”. Direct variation problems are modeled using linear equations in the form of y kx . We first find the value of the constant of variation k ; then, we solve for a specific quantity. Example 1. Solve the variation problem.
