Panlilio Section 1.4 & 1.5 Objectives Translate verbal expressions and sentences into algebraic expressions and equations Solve equations by using the properties of equality Solve equations for a specific variable Solve equations containing absolute value
Panlilio Translating Words into Math Twice the cube of a number Three less than a number is -7 Four times the sum of a number and 2 A number divided by 4 is 2/3 The product of a number and its square
Panlilio Properties of Equality For any real number a, a=a For all real numbers a and b, if a=b, then b=a For all real numbers a, b, and c, if a=b and b=c, then a=c If a=b, then a may be replaced by b For any numbers a, b, and c, if a=b then a+c=b+c and a-c=b-c For any real numbers a, b, and c, if a=b, then a b=b c and, if c 0,
Panlilio Solving Equations Solve each equation:
Panlilio Absolute Value Equations Absolute Value of a Number --> The number of units it is from 0 on the number line Absolute Value Equations --> Two Possible Scenarios: 1. The number inside is positive, or 2. The number inside is negative. Either way, when you take the absolute value, you get a __________.
Panlilio Section 1.6 & 1.7 Objectives Solve inequalities and graph the solution sets Solve compound inequalities using and and or Solve inequalities involving absolute value and graph the solutions
Panlilio Solve each inequality. Graph the solution. Solving Inequalities Reminder! When solving inequalities: if you multiply or divide by a negative number, you have to ________ the inequality sign.
