Good point.

You know what's messed up? My teacher assigned multiple problem sets that she made up herself, and all the problem sets are supposed to have problems of similar difficulty. The first problem set contained these 3 problems: a) |(4/x)| > 5 b) |2x + 1|<= 7 c) (x + 1)(x - 5) < 0 b) and c) are...

Thank you SO much for your help! The hardest part was realizing that even though x was a variable it was still negative... Again, I REALLY appreciate your help! You were great!

|(4/x)| > 5 4/x > 5 4/x < -5 Case 1: x > 0 Case 2: x < 0 Case 1: x > 0 Case 2: x < 0 4/x > 5 4/x > 5 4/x < -5 4/x < -5 4 > 5x 4 < 5x 4 < -5x...

Okay, I understand what you're saying. So: |(4/x)| > 5 4/x > 5 4/x < -5 Case 1: x > 0 Case 2: x < 0 Case 1: x > 0 Case 2: x < 0 4/x > 5 4/-x > 5 4/x < -5 4/-x < -5 4 > 5x...

Oh, so in the second attempt, it should be -5 < 4/x > 5 So in Case 2 of the first method it should be 4/-x > 5, right?

Hi, I'm stuck on the following problem: |(4/x)| > 5 I split it up into two cases, case 1 is x > 0, case 2 is x < 0 Case 1: Case 2: 4/x > 5 4/x < -5 4 > 5x 4 < -5x 5x < 4 -5x > 4 x < 4/5...
