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
NOW JUST GRAPH .
