1 answer

To solve the inequality |x+2|7, we will break it down into two cases based on the properties of absolute values.

Case 1: x+27

  1. Solve the inequality: x+27 x72 x5

Case 2: x+27

  1. Solve the inequality: x+27 x72 x9

Combine the Solutions

From the two cases, we have:

  1. x5
  2. x9

Solution in Interval Notation

The complete solution set can be written in interval notation as: (,9][5,)

Graphing the Solution

To graph the solution:

  • Draw a number line.
  • Shade the region to the left of -9 (including -9, which is a closed circle).
  • Shade the region to the right of 5 (including 5, which is also a closed circle).

Select the Correct Choice

The final answer is: x9orx5 Express your answer in interval notation: (,9][5,)
