Question

what solution set would you graph with a closed circle at -9.5 and a ret extending to the left

Answer 1

To represent a closed circle at -9.5 with a ray extending to the left, you are describing an inequality involving \(x\) that includes -9.5 and all values less than it. The inequality can be expressed as:

\[ x \leq -9.5 \]

In this case, a closed circle at -9.5 indicates that -9.5 is included in the solution set. The ray extending to the left signifies that all numbers less than -9.5 are also included in the solution set.

When graphing this on a number line:

1. Place a closed circle on -9.5 to indicate that this value is included.
2. Draw a line or arrow extending to the left from -9.5 to show that all values less than -9.5 are part of the solution set.
