To solve the inequality \( |x - 5| + 1 > 5 \), we first isolate the absolute value:

\[ |x - 5| > 5 - 1 \] \[ |x - 5| > 4 \]

This inequality indicates that the expression inside the absolute value, \( x - 5 \), is either greater than 4 or less than -4. Therefore, we can set up two separate inequalities:

  1. \( x - 5 > 4 \)
  2. \( x - 5 < -4 \)

Solving the first inequality:

\[ x - 5 > 4 \implies x > 9 \]

Solving the second inequality:

\[ x - 5 < -4 \implies x < 1 \]

So, the solution to the inequality \( |x - 5| + 1 > 5 \) is:

\[ x < 1 \quad \text{or} \quad x > 9 \]

Graphically, this means we have open circles at the points \( x = 1 \) and \( x = 9 \), and the solution set is represented by two separate intervals: \( (-\infty, 1) \) and \( (9, \infty) \).

Based on this analysis, the correct option is:

Option #1: open circles on the end values; two separate solution sets.
