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

\[ |x−5| + 1 > 5 \]

Subtracting 1 from both sides gives:

\[ |x−5| > 4 \]

Now, we can break this down into two separate inequalities:

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

Solving these inequalities:

  1. For \(x - 5 > 4\): \[ x > 9 \]

  2. For \(x - 5 < -4\): \[ x < 1 \]

Thus, the solution set is \(x < 1\) or \(x > 9\).

Now, we can summarize the graph of this solution:

  • For \(x < 1\) (which is an open interval), we would have an open circle at 1.
  • For \(x > 9\) (which is also an open interval), we would have an open circle at 9.
  • Since the solutions don’t include the endpoints, we have open circles at both ends.

Based on this analysis, the correct representation is:

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