Document Summary
Provide a generalization to the terms listed in this section. 3 |8x + 6| 3 = 3 3. A x and and x > a x a. |2x + 4| < 4 and and and and and. 2x + 4 4 > 4 4. 4 + |2x + 4| 4 8 4. |2x + 4| 4 and and and and and. 2x + 4 4 4 4. If both a is any positive number and that x is an algebraic expression then the following will occur: |x| > a is equaled to x < a or x > a. |x| a is equaled to x a or x a. {x | x < 3 or x > 7} ( , 3) (7, ) 4 + 10 |3x 11| 44. 4 + 10 |3x 11| 4 44 4. 3x 11 + 11 4 + 11.
