0<-8b<12 PLEASE HELP Solve compound inequality

OpenStudy (anonymous):

First, you need to "get rid of" that negative sign in front of the "8b"... you do this by multiplying everything by "-1"... but when you do that, you have to reverse the inequalities. 0 > 8b > -12

OpenStudy (anonymous):

Then you can divide everything by 8 to isolate the "b" term.

OpenStudy (anonymous):

So the answer would be 0<1<-12 ?

OpenStudy (anonymous):

No, you can go straight away and simply divide everything by -8. Remember to flip the inequality since you're dividing by a negative.

OpenStudy (anonymous):

im here :D

OpenStudy (anonymous):

LOL can you help me ?

OpenStudy (anonymous):

0<-8b<12 wah we need to do is divide everything by -8 as suck the inequality now becomes 0<b<-1.5 since we divide by negative, we switch the signs so we have 0>b>-1.5 which can be rewritten as -1.5<b<0

OpenStudy (anonymous):

division by negative sign reverse the inequality
