what's the symbol in x + y -5

OpenStudy (anonymous):

please.... I BEG!!!!! :(

jimthompson5910 (jim_thompson5910):

what's that missing symbol?

OpenStudy (anonymous):

omne sec

OpenStudy (anonymous):

x = y < - 5

jimthompson5910 (jim_thompson5910):

x+y < -5 ?

OpenStudy (anonymous):

with a line under "<"

OpenStudy (anonymous):

and don't beg :)

jimthompson5910 (jim_thompson5910):

x+y <= -5 means you have a solid line and you shade below this solid line

jimthompson5910 (jim_thompson5910):

so that rules out choice D because in choice D, they're shading above the solid line

jimthompson5910 (jim_thompson5910):

4x - 5y > -15 turns into y < 4/5x + 3 which means that you shade below the dashed line y = 4/5x + 3

OpenStudy (anonymous):

thats what i thought yay:)

jimthompson5910 (jim_thompson5910):

so it's either A or C

OpenStudy (anonymous):

I got C...

OpenStudy (anonymous):

:)

jimthompson5910 (jim_thompson5910):

that's incorrect

jimthompson5910 (jim_thompson5910):

try graphing x+y = -5 and see where it goes

OpenStudy (anonymous):

damn one sec

OpenStudy (anonymous):

wow i got it now!!! i looked at it wrong
