bookworm14 · Answer

I think this one is c but im not sure

anonymous · Answer

C

bookworm14 · Answer

i have a few more I think this one is A

anonymous · Answer

did you get "no solution" for the first one?

anonymous · Answer

Yes A is correct

anonymous · Answer

second one solve 
$$4x-2=2\
4x-2=-2$$ separately

bookworm14 · Answer

Well I actually got B for the first one but someone told me B was wrong

anonymous · Answer

the absolute value cannot be negative

anonymous · Answer

so it cannot be $-2$

anonymous · Answer

in the second one, looks like A and D are the same

bookworm14 · Answer

but when you put -2 in it become a 2 because of the absolute value, so therfore a negative 2 should work ...... and in the second problem a and d have different nummber lines (different scales)

anonymous · Answer

you lost me
the absolute value of something is always greater than or equal to zero

anonymous · Answer

can you think of a number whose absolute value is $-2$ ? nope, me neither

bookworm14 · Answer

the absolute value of negative 2 is positive 2 so if you insert -2 into the equation it operates in the same way as a positive 2, sorry im trying to explain this the best i can manage

anonymous · Answer

so whatever number you choose for $x$ it will be true that $|3x+2|\geq 0$

bookworm14 · Answer

I see what you mean @pkjag

bookworm14 · Answer

yes i would think so

bookworm14 · Answer

okay so what was the answer for the first one, it wasn't C, so it was B correct? and we are currently on the second one?

anonymous · Answer

you are thinking way to hard
stop thinking like a math student and think like a person
can the distance between your house and your school be $-2$ miles? 
of course not
it has to be positive
similarly $|whatever|$ is always positive, it cannot be $-2$

anonymous · Answer

the answer to $|3x+2|=-2$ is NO SOLUTION

anonymous · Answer

so the answer is c

bookworm14 · Answer

ok so I got it wrong right? and the answer is no solution to the "2nd" problem or the first sry i got a bit overwhelmed for a sec

bookworm14 · Answer

no the first one is C okay yea i think thats right :P 

what was the second one?

anonymous · Answer

repost, one problem at a time

bookworm14 · Answer

im closing this and starting over okay?

anonymous · Answer

k by me
