3.5: Compound Inequalities

Definition Two inequalities that are joined by the word
‘and’ or ‘or’ form a compound inequality. This is for when we want x to be between two
numbers or not between two numbers.

Writing a Compound Inequality All real numbers that are at least -2 and at
most 4
Today’s temp. will be above 32° but below 40°

Solving Compound Inequalities -4 ≤ r – 5 ≤ -1
-6 ≤ 3x ≤ 15

Solving Compound Inequalities 4v + 3 < -5 or -2v + 7 < 7
-2x + 7 > 3 or 3x – 4 ≥ 5

Word Problem The acidity of the water in a swimming pool is
considered normal if the average of 3 pH readings is between 7.2 and 7.8, inclusive. The first 2 readings are 7.4 and 7.9. What are the possible values for the 3rd pH reading?
