Help Sharky and Ducky compare numbers in this inequalities game practicing greater than, less than, and equals.
Solve an inequality that has negative numbers and a variable. This video focuses on using inverse operations to solve for a variable and the importance of flipping the inequality when multiplying or dividing by a negative number.
In this lesson, you will learn how to solve linear inequalities as well as how to graph the solutions on number lines and the XY plane. [8:22]
A solution to an inequality makes that inequality true. Learn how to test if a certain value of a variable makes an inequality true. [5:10]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
A solution is presented to a student-submitted problem. The problem involves graphing and finding the solution set to a system of inequalities.
Practice inequalities with these interactive flashcards; select the number range you prefer and then click the symbol ( or =) that makes the comparison correct.
Find a quick, concise explanation of inequalities. Examples are given and clearly explained.
This tutorial will demonstrate how to graph an inequality and an infinite set on a number line. Closed and open circles are discussed using specific examples. [3:37]
The intersection of two inequalities is what they have in common. This tutorial shows you how to graph two inequalities on the same number line and then find the intersection. [2:40]
This tutorial will teach you how to graph the union of two inequalities using a number line. [2:06]
Watch this video tutorial to discover how to solve an inequality for a variable. Remember to perform the order of operations in reverse. [1:59]
When you graph an inequality on the coordinate plane, you end up creating a boundary which cuts the plane in half. Learn about this boundary in this tutorial. [1:08]
