Add 1
  |2x +3| < 5
Unfold
  -5 < 2x +3 < 5
Subtract 3
  -8 < 2x < 2
Divide by 2
  -4 < x < 1

The solution is
  -4 < x < 1

_____
If you subtract 4 from both sides, you get an expression that compares to zero. Most graphing calculators will show you the zero-crossings, so you can easily find the values of x where this is true.

|2x+3|-1<4
|2x+3|<5

1) when 2x +3 is positive     
2x+3<5
2x<2
x<1    (-∞, 1)

2) when 2x+3 is negative
-(2x+3)<5
-2x-3<5
-2x<8
x>-4  (-4, ∞)

(-∞, 1)∩(-4, ∞)=(-4,1)

The stem-and-leaf plot shows the points scored by Jason in nine basketball games.
Pepsi [2]

Considering the given stem-and-leaf plot, the outlier is given by:

A - 40

<h3>What is an stem-and-leaf plot?</h3>

The stem-and-leaf plot lists all the measures in a data-set, with the first number as the key, for example:

4|5 = 45.

Outliers are usually the lowest or the highest value in the data-set. In this problem:

  • The lowest value is 10, but the second lowest is 12, which is close to 10.
  • The highest value is 40, but the second lowest is 34, which is farther to 40 than 12 is to 10, hence 40 is an outlier.
