I can help! Here, let me have a sec...

OpenStudy (anonymous):

So the first one, 2x + 8 > 6. Subtract 8 from both sides. What is 6 - 8?

OpenStudy (nevermind_justschool):

-2

OpenStudy (anonymous):

Ok lets do the first question and then you do the rest! :) \[2x+8>6\] so solve for x first, and if you have a \[>~ or ~<\] you will have a empty dot, if you have \[\le ~or ~ \ge\] then you will have a black dot and of course these signs show the direction, so solving for the problem, 2x>6-8 => 2x > -2, dividing 2 on both sides, x>-1 so we'll have something like this |dw:1423275496909:dw|

OpenStudy (anonymous):

since x>-1 meaning greater than -1

OpenStudy (anonymous):

Good. Now divide by 2. What is -2 divided by 2?

OpenStudy (nevermind_justschool):

-1

OpenStudy (anonymous):

All you need to do for each problem is solve for x. Then make the graph point in the direction the > sign is pointing. If the sign is ' Or equal go's then it will be a filled in dot. If not, then it is just a circle.

OpenStudy (anonymous):

Don't forget that when you divide by a negative on both sides, flip the sign around.

OpenStudy (nevermind_justschool):

Okay, that makes sense, thanks both of you!

OpenStudy (anonymous):

No problem. :)

OpenStudy (nevermind_justschool):

I got a 100!!!

OpenStudy (anonymous):

Good job!! :D

OpenStudy (anonymous):

Congrats :)

OpenStudy (anonymous):

I want to add to @DuckDynastyfan923 on when you divide by a negative on both sides, the sign flips, this also works with `multiplication`

OpenStudy (anonymous):

Multiplying by a negative number on both sides, the sign flips as well

OpenStudy (anonymous):

Yes, that is true, but I was only seeing that he/she would only have dividing a negative. :)
