Teacher's Aide needs help solving some problems.

[football45013]

Ok, so I am a Special Education teacher's aide. Unfortunately, I have been placed into an Algebra 1 class with lower level students. I am not very happy about it to say the least, but I would like to keep my job, so I just have to deal with it, lol. Anyways, I have not worked with Algebra in years and I never was a math person. I have been tasked with helping a group of students answer some problems related to Absolute Value. The teacher did not leave me a key, so can anybody give me the answers to the questions I have posted below? Thanks a bunch!

FYI: These are absolute value problems. I don't know how to put the straight vertical lines from a keyboard on each side of the number that is supposed to have these lines. So I am just going to use brackets. Thanks.

1.) [-4] times -3 ( then he has a box in the middle) 4 [-2-1]

**I think he wants students to put something in box in the middle of the 2 sets of numbers.

2.) Graph -2<x<4

**He then has a number line underneath with 4 on one side and -2 on the other, with zero in the middle.

3.) graph y=[x+2]

**He then has an x/y chart underneath where x has 2, 1, 0, -1 and -2 underneath and then no numbers underneath y.

I know it's hard to explain without writing it out, but hopefully you guys understand the problems I'm trying to write out. Thanks for any help!

Lacking instructions, it is hard to advise. Please consult with the instructor (and the instructor's teaching materials) for clarification.

2.) Graph -2<x<4

**He then has a number line underneath with 4 on one side and -2 on the other, with zero in the middle.

This is not absolute values; it is linear inequalities. To learn what these are, try here.

3.) graph y=[x+2]

**He then has an x/y chart underneath where x has 2, 1, 0, -1 and -2 underneath and then no numbers underneath y.

Assuming the square brackets are meant to indicate absolute-value bars, you can learn how to graph this here.

Note: The above links assume that you understand the prerequisite material. Since you appear not to, you might be best advised to hire a qualified local tutor and set aside an hour or two a day for concentrated private instruction. With diligent effort and some luck, you should be able to get caught up to the course material in only a few weeks.
