PPT-Solving an Absolute Value Equation

Solving an Absolute Value Equation You have already used graphs and mental math to solve some absolute value equations For instance 8 and 8 This has two solutions Solving an Absolute Value Equation. Lesson Objective:. An equation is like a set of scales.. To keep it balanced, whatever you. do to one side you must do to the other.. Use this idea to solve equations like:. 3x + 1 = x + 7 . 2 (3x + 1) = 3 (x – 2). By: Pedro Cuellar ONLY!. The Golden Rule. Whatever you do to . one side . you do to the other.. 2X+5=15 or 5X-54=130. How would you solve the following two equations? What would be the recommended strategy to find out the answer?. 1. Order the following numbers from least to greatest. . . 15, , -2, , -12, 0, . A dog is standing on a cliff, 35 feet above sea level. A dolphin is swimming 6 feet below sea level. An octopus is moving along the seabed 40 feet below seal level.. 1. 2. Lesson Objective. Students Will Be Able To…. Distinguish comparisons of absolute value from statements about order.. Lesson Description. This lesson contains review of absolute value and magnitude while discussing the language surrounding these concepts that often confuses students. It emphasizes identifying the context of the math in discerning the numerical values coinciding with the verbiage. . 1. 1. 2.. 3. 4.. Absolute Value Equations. 2. Absolute Value Inequalities. Absolute value inequalities are solved in the same way linear inequalities are solved. . Change the inequality to an equality and solve.. Equations. AII.4a – The student will solve, algebraically and graphically, absolute value equations and inequalities. Graphing calculators will be used for solving and for confirming the algebraic solution. . If you read from left to right . 10 . “is greater than “ . 5. . X. If you read from right to left . 5. . “is less than “ . 10. . X. If you read from left to right . 5. . “is less than “ . Solving a Problem by Creating an Equation. Toucans and blue-and-yellow macaws are both tropical birds. The length of an average toucan is about two thirds of the length of an average blue-and-yellow macaw. Toucans are about 24 in. long. What is the length of an average blue-and-yellow macaw?. 1. Order the following numbers from least to greatest. . . 15, , -2, , -12, 0, . A dog is standing on a cliff, 35 feet above sea level. A dolphin is swimming 6 feet below sea level. An octopus is moving along the seabed 40 feet below seal level.. Solving Absolute Value . Inequalities. Situation. The Frito-Lay plant has strict standards when it comes to bagging their products. The weight of the chips in a snack-size bag must be within 0.15 ounces of the advertised size of 1.75 ounces in order to be sent to the store shelf. .
