Compound Inequalities Goal: Write, solve and graph compound
inequalities. Prepare to have your mind blown!!
Slide 2
What are Compound Inequalities? Compound Inequalities: two
inequalities connected by and or or. Example: x is less than five
and greater than -10 or -10 < x < 5

Slide 6
Writing Compound Inequalities (AND) Lets Break it Down
Slide 7
Writing Compound Inequalities (OR)
Slide 8
Real Life Compound Inequalities Write and inequality to
describe the Alpine meadow region. (use y is represent region)
Slide 9
Real Life Compound Inequalities Write and inequality to
describe the Timber Region. (use y is represent region)
Slide 10
Graphing Compound Inequalities AND connect together (one line
segment) OR two separate lines
Slide 11
Lets Try (AND Ex. 1) -2 < x < 5 Break it up: x > -2
AND x < 5
Slide 12
Lets Try (AND Ex. 2) -9 x < -1
Slide 13
Lets Try (AND Ex. 3) -5 x 4
Slide 14
Lets Try (OR Ex. 1) x 4 Break it up: x < -6 OR x > 4
