1 answer

To solve the inequality \( n - 16 \geq -6 \) or \( n + 6 \leq 1 \), we need to solve each individual inequality separately.

Step 1: Solve the first inequality

We start with:

\[ n - 16 \geq -6 \]

Add 16 to both sides:

\[ n \geq -6 + 16 \] \[ n \geq 10 \]

Step 2: Solve the second inequality

Now, we solve:

\[ n + 6 \leq 1 \]

Subtract 6 from both sides:

\[ n \leq 1 - 6 \] \[ n \leq -5 \]

Step 3: Combine the results

The solutions can be summarized as:

  • \( n \geq 10 \)
  • \( n \leq -5 \)

Since this is an "or" inequality, the solution set includes values from both ranges.

Step 4: Graph the solution

On the number line, the solution can be represented as:

  1. An arrow pointing to the right starting at 10 (including 10).
  2. An arrow pointing to the left starting at -5 (including -5).

The graph would look like this:

   |       |     |     |    |      |     |      |    
-10   -5.   0    5  10   15  20  25

Summary of the solution:

  • The solution set is \( n \leq -5 \) or \( n \geq 10 \).
