@Will.H

OpenStudy (risingtotop):

they can explain

OpenStudy (risingtotop):

Will

OpenStudy (risingtotop):

can you explain

OpenStudy (will.h):

Cool question 1st you should solve the inequality Let's solve the 1st shall we X - 3 < -7 Add 3 to both sides to get X < -4 That means a vertical dashed line one X = -4 and the possible solutions are all values less than -4 so shaded to the left Make sense so far?

OpenStudy (risingtotop):

Will i have one more but just tell me if im right please

OpenStudy (risingtotop):

OpenStudy (risingtotop):

A is correct right?

OpenStudy (risingtotop):

and yes makes sense

OpenStudy (will.h):

Correct A

OpenStudy (will.h):

Each of them contains 2 solutions

OpenStudy (risingtotop):

okay good Will do you mind if i send a couple more ? but i have answers for them

OpenStudy (risingtotop):

I just dont want to take advantage of you but at the same time i need to be sure they are right

OpenStudy (will.h):

Sure Go ahead

OpenStudy (will.h):

Let me know when you want me to continue solving the 1st question

OpenStudy (risingtotop):

okay right after this

OpenStudy (risingtotop):

OpenStudy (risingtotop):

are they all correct?

OpenStudy (will.h):

All except the last one

OpenStudy (will.h):

The last one is -16

OpenStudy (risingtotop):

3?

OpenStudy (will.h):

Confirm by substituting x = -16

OpenStudy (risingtotop):

woah!

OpenStudy (risingtotop):

hold on let me do it

OpenStudy (will.h):

Go ahead

OpenStudy (risingtotop):

you're correct

OpenStudy (risingtotop):

thanks to you omg

OpenStudy (will.h):

Great :)

OpenStudy (will.h):

Need help with anything else before I go off?

OpenStudy (risingtotop):

Yes if you dont mind

OpenStudy (risingtotop):

the first problem can we continuing solving it

OpenStudy (will.h):

Oh yeah. I forgot

OpenStudy (will.h):

We did solve the 1st inequality And since there is no bigger than (or equal to) then that means it is an open circle x < -4 An open circle on -4 and shading to the left because it is" less than" Making sense so far?

OpenStudy (risingtotop):

okay yes

OpenStudy (risingtotop):

It says OR!

OpenStudy (will.h):

Fantastic Now let's work on the other inequality X + 5 bigger than or equal to 8 Let's solve this one as well Subtract 5 from both sides So x is bigger than or equal to 3 That means a "closed circle" because of the "or equal to phrase" on 3 And since it is bigger than or equal to 3 then that means it will have all positive numbers bigger than or equal to 3 as solutions. Then that means it is shading to the right That means option A is the correct one Hope it helps

OpenStudy (risingtotop):

okay i get it

OpenStudy (risingtotop):

okay 1 more and i swear you can get off its really fast

OpenStudy (will.h):

Lol. Okay

OpenStudy (risingtotop):

i just need to make sure the guy who helped me did it right

OpenStudy (risingtotop):

OpenStudy (will.h):

Yes it is indeed correct

OpenStudy (risingtotop):

Okay good NOW GO!

OpenStudy (risingtotop):

Thanks for the help

OpenStudy (will.h):

Lol. My pleasure.
