You can take a pic of work to share solutions with others, or even better, to point to a place where you have a question

With the three dot menu option, you can add video. Be appropriate!

Question

I'm not sure I'm understanding the inequality rule where if you're multiplying or dividing by a negative number the symbol is swapped

Practical Inequalities

mateo_rekow — 2020-04-08 02:12:35 UTC

What are some real-life situations in which inequalities could come in handy? I don't know of any uses other than knowing the range of some given variable.

Question

beauschaumburg — 2020-04-08 06:08:31 UTC

Do we switch the sides of the variable if it ends up on the left side of the > symbol? If yes then how?

question

amberochs — 2020-04-08 15:19:44 UTC

I don't have that kind of calculator, is there some thing I could look up to do that or can I still do it on a TI-30XII S?

Question

deviholdsworth — 2020-04-08 16:54:35 UTC

Similar to Rayne, I'm still trying to figure when and how the the greater than or less than sign is swapped. On certain problems it would make sense but on other it would really confuse me.

Compound Inequalities

I am having trouble understanding how and when the symbol is swapped when you are dividing a negative number.

further questioning

2020-04-08 17:11:56 UTC

specifically, question #7 on the compound inequalities worksheet. if -3v-2 is greater or equal to -2. Then -3v is greater or equal to 0, which then I would divide -3v by -3 to isolate v and then divide 0 by (-3) which is 0. which would lead mw to assume v is equal or greater to 0. But under the graph is states v is less than or equal to 0. Why did the symbol change?

question

katelynpatchell — 2020-04-08 17:41:29 UTC

When it comes to swapping the greater than or less than sign, you only do so when dividing by a negative??

Question

zuriallamour — 2020-04-08 18:20:23 UTC

Will it be beneficial/ important for us to make sure we are always keeping the variable on the left side of the expression? For example, if the expression given is 3 < -5n + 2n, is it important for us to rewrite it as - 5n + 2n > 3 so that the variable is on the left?

Question

katnguyen2 — 2020-04-08 18:27:16 UTC

With the problems that have multiple greater than signs can we treat them like they are two different problems and combine one they are solved separately or should we solve all together?

katelynpatchell — 2020-04-08 19:36:22 UTC

confused about how to do compound "and" inequalities

Question

tatewagner — 2020-04-08 23:31:57 UTC

Is it possible that when you need to move the variable to the left side, you can add it to the number already there, but switch its sign? For example, if 23 < 6b - 7, -6b + 23 < -7. How does that work?

question

railajaffer1 — 2020-04-09 15:50:24 UTC

When solving the inequalities, when the problem has "or" in it and multiple greater then and less then signs, do we solve them together or separately?

Question

2020-04-09 19:10:09 UTC

Is it necessary to have the 'dash' beneath the greater than or less than symbol? If so, how would this impact an equation if removed?

Hi Mr. Meek, I was woundering what notación you wanted us to use in the Multi-Step Inequalities worksheet, regular or interval notacion?

Question about Compound Inequalities (specifically "or")

bennetthart — 2020-04-09 22:54:33 UTC

How do I know which inequality a variable should satisfy? For example, on question #1 I got m is less than -6 or m is greater than 8. I'm not sure what inequality to go with, though I may have just made a mistake

Tips for keeping these worksheets organized

2020-04-10 20:48:15 UTC

Hi guys! As I was finishing the worksheets for compound inequalities, I realized that it might be a bit confusing without keeping it organized. So here are a few tips I gathered from doing the worksheets on how to keep from confusing yourself:
1. Keep a straight edge with you at all times,I found this useful for the number lines and for keeping my equations in order
2. I also like to draw lines in between problems, skipping a line after each one.
3. I also made sure to keep the number lines with an odd number of spaces that way you have a middle with an even number of spaces on both sides
Hopefully these little tips help you guys out

answer to questions

mychalbishop — 2020-04-11 03:46:56 UTC

i think i might have gotten a serviceable answer to rayne and devi's questions:
lets say you have X (-2) and Y (-5), X has a lower absolute value so will always be closer to 0 then Y, when they're negative this sets X greater than Y, but this flips when both become positive, making X less then Y

Question

raynemccollough — 2020-04-17 23:17:26 UTC

Is there a way to tell if a equation of a line represents a vertical or horizontal line when it's in Standard form
