nopes @miteshchvm

anonymous · Answer

-c < -7 therefore 
if we multiply be -1
we get c > 7 
i ought to correct myself ;)

@TheViper and @hartnn how did you prove c > -7 !?
its totally wrong as per i observed the solution, i suggest you to look at it once again

anonymous · Answer

would the arrows on the graph be like <------  ------> or
o-----------o

nubeer · Answer

well c > 7

theviper · Answer

if   -c<-7
then   c>-7

nubeer · Answer

and arrows would be like the second one.

o---------------o

anonymous · Answer

right?

anonymous · Answer

@TheViper  whats the logic in that?
you can't change one sign. you need to change it for whole function

nubeer · Answer

when we remove negative its basically multiply by -1 and the equality signed is reversed.

nubeer · Answer

@BarbieGurl  yes right.. we use hollow circles when < and filled circles  for <= or =>

anonymous · Answer

-c < -7
-(-c) > -(-7)
c > 7
thats it!! XD

anonymous · Answer

$$9-c <2$$ $$-c <2-9$$ $$-c <-7$$ $$-(c)<-7$$ $$c >-7/-1$$ $$c >7$$
