Good.
OpenStudy (anonymous):
it sure dnt give u really any information does it?
OpenStudy (anonymous):
So then use any pronumeral. you can use x or z whatever.
OpenStudy (anonymous):
So what does the uncoloured circle mean? Does it mean it's include which means that it's
\[\le \] or does it mean it's not included meaning it's \[<\]
OpenStudy (anonymous):
included

Choose your option @Umar97
OpenStudy (anonymous):
umm "<"? I havent really studied this yet.
OpenStudy (anonymous):
GOod job.
OpenStudy (anonymous):
Remember, coloured circle means it's included.
OpenStudy (anonymous):
If it's not coloured it's < or >. Okay. Now, So we finally have this:
x<?

All wee need to do is fill in that question mark with a number.
OpenStudy (anonymous):
What number is the circle on?
OpenStudy (anonymous):
-1
OpenStudy (anonymous):
Good. You just owned it. SO now you know the circle is on -1 what number would we fill the question mark with?
OpenStudy (anonymous):
x < -1

Yes!! Bravo. You go it.
OpenStudy (anonymous):
you got it*
OpenStudy (anonymous):
but theres no option for this answer :O
OpenStudy (anonymous):
What are the options?
OpenStudy (anonymous):
Is it a different pronumeral or something?

OpenStudy (anonymous):
x + 9 < 10
x + 7 < 6
x - 8 > -9
x - 5 ≤ - 6
OpenStudy (anonymous):
Okay we got this right? x < -1
OpenStudy (anonymous):
That's what we're looking for. ALl we need to do with those options is move the number to the RHS so that we solely have x on the LHS(Left Hand Side)
OpenStudy (anonymous):
So I will do the first option:
\[x+9<10\]
\[x+9-9<10-9\]
OpenStudy (anonymous):
\[x<10-9\]

OpenStudy (anonymous):
\[x<1\]
OpenStudy (anonymous):
That's the first option/ x<1 does not match what we found which was x<-1
OpenStudy (anonymous):
ohh you have to do all of them till you find the one that matches?
OpenStudy (anonymous):
Yep.
OpenStudy (anonymous):
okay thanks, you helped me alot! :)
