Dr. Eaton covers Compound Inequalities by first explaining what exactly is a Compound Inequality. Then you will cover the two cases when inequalities are joined by 'And' or 'Or.' Four extra examples at the end of the lesson make sure you have a great grasp of the ideas.
inequality combines two inequalities using either and or or.
First solve each inequality separately. If and was used, the
solution set is the set of all numbers in both solution sets of the
two inequalities. If or was used, the solution is all numbers
in either or both of the solution sets of the two inequalities.
The solution of a
compound inequality can be found by simplifying each inequality
algebraically and then graphing the simplified inequalities.
solution set of a compound inequality using either a number line or
set builder notation.
