TSW#3 Solving Compound Inequalities JH&HK

2
Vocabulary Compound Inequality: Two inequalities connected by and/or n=number Less than: x

3
Solving compound Inequalities 1.All real numbers are greater than 0 and less than or equal to 4 2.All real numbers are less than -1 or greater than 2 0

4
Graphing This inequality is also written as 0

5
Revising Both Inequality Symbols Solve 3<-x+28. Graph the solution Isolate the variable x between the two inequality signs. Solution 3<-x+28 1<-x6 -1>x-6 Write original inequality Substitute 2 to each expression Multiply each expression by -1 and reverse both inequality symbols

6
Revising Both Inequality Symbols Graph The solution is greater than -6 and less than or equal to -1 -1>x>-6
