@3mar

OpenStudy (itrymath):

hi'

OpenStudy (3mar):

Well, I am here

OpenStudy (itrymath):

lol you must be so tired of me taging you every 1 or 2 hours even half hours :P

OpenStudy (itrymath):

can you help please :)

OpenStudy (3mar):

As I am used to, I will simplify it then look at the choices. ok?

OpenStudy (itrymath):

no i get that part but i dont get the line graph its confusing

OpenStudy (3mar):

I am at your service. Won't be late for any help as I can.

OpenStudy (itrymath):

okay i simplified

OpenStudy (3mar):

so what is the final form you got?

OpenStudy (3mar):

Be sure that is correct, ha ;)

OpenStudy (itrymath):

i got P greater than -2 and I got P less than 5

OpenStudy (itrymath):

if i even did the sign correctly aha

OpenStudy (3mar):

like that\[-2<p<5\]?

OpenStudy (itrymath):

\[p >-2 and p\]

OpenStudy (itrymath):

oops

OpenStudy (3mar):

what?

OpenStudy (itrymath):

\[p >-2 and p <5\]

OpenStudy (itrymath):

this stuff is so hard to use

OpenStudy (3mar):

like I wrote or not?

OpenStudy (itrymath):

like you wrote correct

OpenStudy (3mar):

Ok

OpenStudy (3mar):

Hint: as the two signs are just < and > (don't contain =), the points -2 and 5 are hollow (not included). Got that?

OpenStudy (3mar):

by the way, what is your choice?

OpenStudy (itrymath):

um

OpenStudy (itrymath):

hollow?

OpenStudy (3mar):

I mean it is not with us (not included in the solution)

OpenStudy (itrymath):

my choice is D

OpenStudy (3mar):

Thank you for the medal! What matters is that got the idea and can solve such this yourself.

OpenStudy (3mar):

I don't think so.

OpenStudy (itrymath):

so am i right :)

OpenStudy (3mar):

For D, it means that \[p \le 5\] but we have gotten that \[p<5\] so 5 is out of our solution and it should be like a hollow point.

OpenStudy (3mar):

Hope that helps

OpenStudy (itrymath):

B

OpenStudy (itrymath):

it has to be B

OpenStudy (itrymath):

lets name the answer choices 1 2 3 and 4 i choose 1 for my answer

OpenStudy (3mar):

Yes, correct. first choice..05_02_11b.jpg

OpenStudy (3mar):

OpenStudy (itrymath):

sure

OpenStudy (itrymath):

OpenStudy (3mar):
