A discussion on how to solve linear and nonlinear inequalities is presented. Both the Test Method and the Factor Method of checking positive/negative intervals are included as part of the discussion.
Students are introduced to integers and rational numbers, extending the number line to include negative values, understanding the order of rational numbers, and interpreting them in context.
Flexbooks 2.0 are interactive, customizable, digital textbooks. Flexbooks are standards-aligned. Flexi, a student tutor, is integrated into each book to guide you on your learning journey. Flexi can assist in learning, answer questions, and check your understanding of the material. This Flexbook covers topics related to sociology.
A free CK-12 account is required to view all materials.
Students hone their skills of solving multi-step equations and inequalities, redefining their definition of "solution" to include cases such as infinite solutions, and interpreting solutions in context.
Linear inequalities can be represented both graphically and algebraically. In this video, you will learn how to express linear inequalities as an equation and on a number line. [8:15]
Let's practice some two step equations, some of which require merging terms and using the distributive property. [13:50]
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.
In the period after the Civil War in the American South, when Southern society reorganized to account for the end of slavery. In this video, Kim discusses how many Southern governments passed laws preventing African Americans from voting, among other things, which prompted Congress to pass the Fourteenth Amendment. [5:46]
