What solution set would you graph with a closed circle at −9.5 and a ray extending to the left

A closed circle at \(-9.5\) indicates that the point \(-9.5\) is included in the solution set. A ray extending to the left indicates that all values less than \(-9.5\) are part of the solution set.

The solution set can be expressed in interval notation as \((-\infty, -9.5]\).

In terms of inequalities, the solution set can be written as:

\[
x \leq -9.5
\]

This means that you would graph a closed circle at \(-9.5\) and shade to the left, indicating all values less than or equal to \(-9.5\).
