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
Any help is appreciated !
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.
