Thread: 3+2|9+n|<-1?

1. 3+2|9+n|<-1?

ok so on my hw i have this question: 3+2|9+n|<-1. The < is less than or equal to but I don't know how to make the line underneath. Anyways I got n<-11 & n>7. Is that right? And if not how do you solve this then?

If the problem is $3+2|9+n|\le -1$ then there is no solution.

the instructions are to solve each inequality and graph its solution. How is there no solution?

We're adding a positive value (3) to another non-negative value. Therefore the LHS can never be less than 3 and so no values of n satisfy this inequality
