ABSOLUTE VALUE EQUATIONS AND INEQUALITIES 03 To solve an absolute value equation isolate the absolute value on one side of the equal sign and establish two cases. A b a b Set the expression inside the absolute value symbol equal to the other given expression. A b a -b Set the expression inside the absolute.

In the previous lesson students solved absolute value equations. Today the students start by graphing these equations to find the solutions. For detailed presentation notes please see the PowerPoint.

This is my students first opportunity to look at the graph of absolute value. Once they have looked at the graphical solutions to a variety of absolute value equations with and without extraneous solutions we will move on to inequalities. 17 solving absolute value equations inequalities Powerpoint Presentation.

17 Solving Absolute Value Equations Inequalities p. 50 Learning Check I can solve absolute value equation. Absolute Value of x Symbol lxl The distance x is.

-3y -8 90 That means we will have one inequality that just gets rid of the absolute value signs. And one that gets rid of the absolute value sign and. Flips the inequality symbol to the other direction.

And changes the sign of the right hand side. -3y -8 90 -3y -8 -90 becomes. And Create two related inequalities Here we have GREATER THAN so we are going to See you later man.

3x 6 5 7 Solving Graphing Absolute Value Inequalities Solving an Absolute Value Inequality. Rewrite the inequality as a conjunction or a disjunction. If you have a you are working with a conjunction or an and statement.

Less thand If you have a you are working with a disjunction or an or statement. In the second equation you must negate the right hand side and reverse the direction of the inequality. X 0 -2 2 This absolute value inequality represents all of the numbers on the number line whose distance from 0 is more than 2.

Notice that the intervals satisfying this inequality are going in opposite directions. X -2 or x 2 x x 0 -2 2 This absolute value inequality represents all of the numbers on the number line whose distance from 0 is more than or equal to 2. Notice that the intervals satisfying this inequality.

This solution is called the feasible region. Graphing a Linear Inequality 1 Solve the inequality for y or for x if there is no y. 2 Change the inequality to an equation and graph.

3 If the inequality is or the line is dotted. If the inequality is or the line is solid. Graphing a Linear Inequality Graph the inequality 3 - x 0 First solve the inequality for x.

3 - x 0 -x -3 x 3 The point of intersection is. Petes PowerPoint Station is your destination for free PowerPoint presentations for kids and teachers about Inequalities Absolute Values and so much more. 92 Absolute Value Equations and Inequalities.

92 Absolute Value Equations and InequalitiesUse the distance definition of absolute valueObjective 1 Slide 92- 2The absolute value of a number x written x is the distance from x to 0 on the number line. For example the solutions of x 5 are 5 and 5 as shown below. We need to understand.

FREE Solve Absolute Value Inequalities PowerPoint Your students will enjoy learning and practicing how to solve absolute value inequalities with this fun colorful animated PowerPoint presentation. The PowerPoint has 3 instructional slides including examples that explain why and how you must set up the two inequalities to solve the problems. Absolute Value Equations And Inequalities.

Solving Absolute Value Equations. Learning Intentions The student will solve algebraically and graphically absolute value equations and. Absolute Value is the distance a number is from zero.

Remember distance itself is ALWAYS positive How do we denote absolute value. SO lets try a few. In math a negative sign in front of the absolute value sign should be read take the opposite of.

This means treat the absolute value sign like a grouping symbol. Do the work inside first THEN take the opposite of Lets try a few What if the variable is in the absolute value. Once the students have gone through this introduction to absolute value equations there are three additional modeling situations temperature assessment grades and biology Math Practice 4.

The first two problems are relatively simple. My goal with these problems is to give the students an opportunity to experiment with building the absolute value models. Students will struggle with.
