Solving an inequality?

OpenStudy (ja1):

OpenStudy (maeganr):

-8 is less than or equal to 2x - 4 < 4

OpenStudy (maeganr):

< with a line under it ^^^

OpenStudy (ja1):

you mean <=

OpenStudy (ja1):

ok so you want to solve it yourself or you want the answer?

OpenStudy (maeganr):

OpenStudy (ja1):

oops

OpenStudy (ja1):

ok but do you want to know how i did it or just the answer with work

OpenStudy (ja1):

you know whats funny im learning this right now, on a seperate tab XD

OpenStudy (ja1):

what?

OpenStudy (maeganr):

-8≤2x-4<4

OpenStudy (ja1):

lol ok

OpenStudy (maeganr):

yeah so can you show how you get the answer and the answer?

OpenStudy (ja1):

maybe just a sec

OpenStudy (maeganr):

ok

OpenStudy (ja1):

so im guessing your doing compound inequalities correct and thanks for the testimonial :)

OpenStudy (ja1):

ok got it its: \[-4 \le x<2\]

OpenStudy (maeganr):

Well actually we did it in October, but Im doing an Error Analysis on all my work for the 2nd Quarter because I need a B. and I have a 72. C in Algebra. :O

OpenStudy (maeganr):

OpenStudy (maeganr):

Thats not one of my answer choices..

OpenStudy (ja1):

oh no :O i forgot the -4 grrr.... let me redo it

OpenStudy (maeganr):

A. 0≤x<6 B. -2≤x<0 C. -2≤x<4 D. -6≤x<-2 B is NOT correct either, because thats what I put and got it wrong. :|

OpenStudy (ja1):

ok now i got it XD its c let me show you the work just a sec

OpenStudy (maeganr):

Ok

OpenStudy (ja1):

-8≤2x-4<4 +4 +4 +4 -4≤2x<8 Seperate the inequality: -4≤2x 2x<8 /2 /2 /2 /2 -2≤x x<4 Combine Inequality: -2≤x<4

OpenStudy (ja1):

pardon my messiness :)

OpenStudy (maeganr):
