What does the symbol '≥' indicate in an inequality?

Back

It indicates that the value can be greater than or equal to a certain number.

Front

What is a compound inequality?

Back

An inequality that combines two or more inequalities, often using 'and' or 'or'.

Front

When do you use 'and' in absolute value inequalities?

Back

You use 'and' when the absolute value expression is less than or equal to a number, creating a range of values.

Front

When do you use 'or' in absolute value inequalities?

Back

You use 'or' when the absolute value expression is greater than a number, indicating two separate ranges.

How do you solve an absolute value inequality of the form |x| < a?

Back

Split it into two inequalities: -a < x < a.

Front

How do you solve an absolute value inequality of the form |x| > a?

Back

Split it into two inequalities: x < -a or x > a.
