Question

three ways to represent the same solution set are shown, but one may contain a mistake. is there a mistake?
the arrow on the number line is going in the wrong direction.
the numbers in the interval notation should switch places.
the circle on the number line should be filled in.
there are no mistakes.

Explanation:

Step1: Analyze interval notation

For the inequality \(x < - 22.9\), the interval notation should be \((-\infty,-22.9)\). The given interval notation \((-22.9,-\infty)\) has the numbers in the wrong order. In interval notation, for \(a < b\), the interval \((a,b)\) represents \(a

Step2: Analyze the number - line

The open - circle (not filled - in) at \(-22.9\) is correct for the inequality \(x < - 22.9\) (since \(x=-22.9\) is not included in the solution set). The arrow on the number - line going to the left (towards \(-\infty\)) is also correct for \(x < - 22.9\)

Answer:

The numbers in the interval notation should switch places.
