amistre she has to answer 'AND'
OpenStudy (amistre64):
0 < -|2| ; i shaded a wrong area lol
OpenStudy (anonymous):
y < -3 means in quadrants III or IV since below the x axis.
OpenStudy (anonymous):
thats what i was confused
OpenStudy (anonymous):
but the absolute is where i am stuck

then the second inequality says -x-2<y<x+2
OpenStudy (amistre64):
OpenStudy (anonymous):
so has be in quad III
OpenStudy (anonymous):
oh damn
OpenStudy (anonymous):
my mistake. first one says y > -3 sorry

(0,0) is a false solution to the abs...
OpenStudy (anonymous):
sorry sorry i messed up
OpenStudy (anonymous):
your sleepy aren't you satellite lol
OpenStudy (amistre64):
and I lifted instad of sepereted my graph...
OpenStudy (anonymous):
lol back at square one

lol..... maybe ;)
OpenStudy (amistre64):
..ammendment D lol
OpenStudy (anonymous):
no moving towards the final solutions;)
OpenStudy (anonymous):
yes it is 3 and 4. y =- |x+2| upside down v at (-2,0) so y<-|x+2| everything below that. must be in 3 or 4. there is just a tiny piece in 4
