Texas Instruments: Direct, Inverse, and Joint Variation

In this variation worksheet, students solve twenty-two direct, inverse, or joint variation problems.  Answers to the first fifteen problems are provided.

Scholars determine how two quantities vary with respect to each other. They complete a fill-in-the-blank activity by stating whether the entities vary directly, inversely, or jointly, create equations that match different variations, and...

Video determining whether a table of values shows direct, inverse, or joint variation and setting up an equation to represent the data. Gives an overview of each type of variation before solving problem. [5:30]

Students engage in a instructional activity that has them practice solving equations using multiplication and division. They practice solving problems using the properties needed and then students practice changing word problems into an...

Students use a graphing calculator to explore the relationship between the linear factors of a quadratic function and its zeros. They learn that the x-intercepts and axis of symmetry of a quadratic function can be determined from its...

Learners use a pair of sliders to investigate how changes in a variable affects other variables in joint variation. A set of five challenge questions tests understanding.

Based off of the hit television show NUMB3RS, this lesson exposes students to equations of variation (direct, inverse, and joint) in the real world, as well as having students work with such equations in the real world context. The...

Twenty-nine problems present a variety of practice working with direct, inverse and joint variation. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the...

This set of questions pertains to definition of functions, relations, inverses, and composition. Questions are multiple choice, true/false, and short answer. Solutions and explanations are included.

Given a conditional statement, the student will write its converse, inverse, and contrapositive.
