l y + 4 l < 1 I know the answer ( -5 < y < -3 ) I just need to know the steps to get to that answer.
l y + 4 l < 1 what you do, since it is an absolute value you set it equal to 1 (the way it is now, and to -1 AND THEN solve each.... y + 4 < 1 or y + 4 > -1 subtract 4 from both sides in each of these..... @leogrrl01, understand?
@SolomonZelman < is a conjunction NOT a disjunction
Let's start over.
I didn't know you had to make two separate ones. Thanks again :)
|x|< 3 means that x is a number that is less than 3 units from 0. Obviously, those numbers are between -3 and 3. So we write: -3<x<3
So for |y+4|<1 we know that y+4 must be between -1 and 1 and so we write: -1<y+4<1 Now subtract 4 from all three parts of the inequality.
@Mertsj, so how is what I was getting different from what you got?
if you get -5<y<-3 Writing wise yes, but they understood how to do it..........
@SolomonZelman AND THEN solve each.... y + 4 < 1 or y + 4 > -1 So y<-3 or y>-5 That is the solution your post leads to. So the solution, according to you is all real numbers:
