A S 6.3 Solve multistep Inequalities.notebook 1 January 19, 2017 Sep 75:46 AM Today's Lesson : Let us remember we are in the holy presence of God * Section 6.3 Solving Multistep Inequalities * Quiz Section 6.1 to 6.4 (Yellow Class) Next Wednesday (Blue Class) Next Friday Instructions : Person doing pray to the podium * Grade Assign #57 4 minutes Assign #57 answers : (out of 14) 11/14 4) x>30 6) w<200 8) r> 8 10) m> 2 12) n<27 14) v< 32 16) d> 37.2 18) k< 0.49 20) x> 37.5 22) y< 45 24) p< 0.38 26) t<0.61 30) 8x>50, x> 25 / 4 32) v < 18, v>162 9 Jan 1910:18 AM Sep 75:46 AM Section 6.3 Solve multistep Inequalities I can solve inequalities using adding, subtracting, multiplying and dividing Similar to "=" equations we solve by doing the same thing to both sides of the "<, < , >, > " inequalities. BUT remembering if we multiply or divide by a negative we flip the inequality. MultiStep Checklist: (not all steps may be needed) * Simplify each side of the inequality (distributive property and or combine like terms) * Move all variables terms to one side of the inequality (adding/subtracting) * Move all constant terms (numbers without variables) to the other side of the inequality (adding/subtracting) * Undo Multiplication/Division of the variable's coefficient (Number attached to the variable) Sep 75:46 AM Important Recall with "=" equations we had "No Solutions" and "Infinite Solutions", the same is true for "<, < , >, > " inequalities If when solving: same "inequality sign" same then "infinite solutions" ex) 2(x5) > 2x 10 NOTE: graph of solutions looks like... If when solving: inequality sign makes no sense then "no solution" ex) 3x+2 > 3x+15 NOTE: graph of solutions looks like... Section 6.3 Solve multistep Inequalities I can solve inequalities using adding, subtracting, multiplying and dividing 0 0 Sep 75:46 AM Ex) 1 (3x + 6) > 1 3 Ex) 2x 5 < 12 Homework Examples : Solve the inequality (variables on one side) Section 6.3 Solve multistep Inequalities I can solve inequalities using adding, subtracting, multiplying and dividing Ex) x + 3 5x > 17 Sep 75:46 AM Ex) 5n < 2(n6) Ex) 17c+9 < 8c2 Homework Examples : Solve the inequality (variables on both sides) Section 6.3 Solve multistep Inequalities I can solve inequalities using adding, subtracting, multiplying and dividing
