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?

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

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!

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
