Do you know how to start it?
OpenStudy (ibeyoshiii):
I wish I did. :/
OpenStudy (anonymous):
Alright treat each equation as a separate one and solve for b in each
OpenStudy (ibeyoshiii):
Okay.
OpenStudy (anonymous):
Ill do the first, 6b < 24
6b < 24
/6 /6
b<4

< is a closed or open circle?
OpenStudy (anonymous):
its open because it isnt equal to.
OpenStudy (ibeyoshiii):
Okay. Thanks.
OpenStudy (anonymous):
No problem! After that, since it is or, you will just say b<4 or (whatever you get in the second part)
OpenStudy (ibeyoshiii):
4b + 12 > 4.
-12 -12
4b > -8
/4 /4
b > -2
That correct?

yep, so did the original equation say "or", or did is say "and"
OpenStudy (ibeyoshiii):
Or.
OpenStudy (anonymous):
alright, so it can't be both at the same time, does that make sense?
OpenStudy (ibeyoshiii):
I guess so. Yeah.
OpenStudy (anonymous):
Alright and just combine the two for your answer

you cant combine them like an and though
OpenStudy (ibeyoshiii):
Okay. Thanks a lot! I appreciate you helping me.
OpenStudy (anonymous):
it will just be "b < -2, or b > 6
OpenStudy (anonymous):
No problem, good luck!
OpenStudy (ibeyoshiii):
Alright. Thanks.
