2. 2. Extra Credit Note: *All those who submitted answers last week were correct. This week’s extra credit to be posted today. Also @ the v6math site: Complete step-by-step guide to Absolute Value Equations & Inequalities Sample Questions and Answers; view the slideshow online or download it to your computer.
3. 3. Where is This?Garapan, 1936
4. 4. Warm - Up: Multi-Step with Distribution −(−5q+1)=−4(7−8q) 2. −2(4k+1) = −10k − 101. −(−5q+1) = − 4(7−8q) 2(4k+1)=−10k−10
5. 5. Warm-Up Questions 2. 2x - 5 + x - 7 = 8 - 5x + 4 3. 3(2x + 5) = 3(x - 2) Thursday is the mid point of the 1st quarter. Write a fraction showing what part of the school year we have completed. 4. True or False: |-x| = |x| Why or Why Not?
6. 6. Practice Problems: Equations with Fractions 3x + 9 = 36; 3x = 27; x = 9
7. 7. What are the steps to solve an absolute value equation? 1. Isolate the Absolute Value | |on one side. 2. Split the Absolute Value into two equations. 3. Solve for the positive exactly the way it is written. 4. Solve for the negative by taking the opposite of the absolute value. 5. Check your answers by plugging them in! 1. Solve: |x+ 5| = 3 2. Solve: |4x - 1| = 19 3. Solve: 5|x + 3|- 3 = 7 Remember: You always solve 2 equations with Absolute Value Equations.
