Solve |d|-|13-8|+|3|<0: Multiple Absolute Value Inequality

Question

Given:

d138+3<0 |d|-|13-8|+|3|<0

Which of the following statements is necessarily true?

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Simplify the constants in the inequality.

  • Step 2: Rearrange the inequality into a solvable form.

  • Step 3: Analyze the resulting inequality to find the acceptable range of d d .

Now, let's work through each step:
Step 1: Calculate the absolute values:
- 138=5=5 |13 - 8| = |5| = 5
- 3=3 |3| = 3

So the inequality becomes:
|d| - 5 + 3 < 0

Simplify the constants:
|d| - 2 < 0

Step 2: Rearrange by isolating d |d| :
|d| < 2

Step 3: Solve |d| < 2 :
The expression |d| < 2 results in the inequality -2 < d < 2 .

Answer

-2 < d < 2
