I know The answer for these question , but the graph missed ,,,So >> The question here is to Graph the answers


Here is the answer


a) |2y+5|>1

so -1 <2y+5< +1

-6<2y<-4


so -3<y<2 answer


b) 7+ |3y-2| <= 10


|3y-2| <= 3


-3<3y-2<3

-1<3y<5


so -1/3 < y < 5/3



c) |6x+5| >= -5


5 > 6x+5 > -5

-10 < 6x < 0

-10/6 < x



d) |3x| < -1


not possible a positive quantity can not be negative
