Write the solutions in interval notations.

a) 0 < absolute( 2x + 1) < 7

b) absolute ( 4 - 7x) less than or equal to 1.9

How do I solve inequalities with absolute values in them (Doh)

Any help is appreciated !

Ouch! They were supposed to explain that to you before they assigned questions on it! (Surprised)

To learn how to solve absolute-value inequalities, try**here**. (I am assuming that you're familiar with regular**linear inequalities**and with how absolute values work.)

Once you've studied the basic terms and techniques, please attempt the exercises. If you get stuck, you can then reply with a clear listing of your steps and reasoning so far.

Thank you! (Wink) - Sep 22nd 2009, 08:49 AMletzdiscuss
