Compound Inequalities

A compound inequality is a statement in which two inequalities are combined into one statement.

• True

• False

A conjunction is a compound inequality that uses the word "or."

• True

• False

Write the compound inequality x < 3 and x > -2 using proper notation.

• -2 < x < 3

• 3 > x > -2

• 3 < x < -2

• -2 > x > 3

The solution region of a compound inequality with the word "OR" is the intersection of the solution regions for the separate parts of the compound inequality.

• True

• False

•  $x\le-1$  

•  $x\ge6$
