For example, a solution to the inequality < 1. may be 0 since 0 is indeed less than 1. !Hl.2;6piJ Two inequalities are equivalent if they have the same solution sets. The book explains many basic techniques for proving inequalities such as direct comparison, method of magnifying and reducing, substitution method, construction method, and so on. endobj Need to be cognizant of the relationship. substituted for the variable, results in a true inequality.

a) 11x 4 = 29 b) 5 + 4x = 11 ute your microphone unless you are Whenever we multiply an inequality by -1, the inequality sign flips. Students must determine which symbol (>,< or =) should go in the blank for each problem. A.8 Interval Notation and Solving Inequalities 2010 5 September 22, 2010 Sep 11:52 PM Properties of Inequalities Nonnegative Property: (for any real number a) a2 > 0 Addition Property of Inequalities: (for real numbers a, b and c) if a b, then a + c b + c if a > b, then a + c > b + c These notes are also helpful for competitive exams such as . 0000059327 00000 n
