Chapter 6 Section 3 Solving Compound Inequalities
Compound Inequalities • Consists of 2 inequalities connected by an “and” or “or” • Example: “And” “Or”
“And” Problems • Both Inequalities must be true • The graph overlaps (in the middle) • The Inequality signs point in the same direction
Examples: • 1. • 2.
Examples: • 3. • 4.
“Or” Problems • One of the Inequalities must be true • Graph can be wherever
Examples: • 1. • 2.
Examples: • 3. • 4.
