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):

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
