The description you provided indicates that the inequality is represented by an open circle at -15.33 and an arrow pointing to the left. This suggests that the values of x are less than -15.33, but not equal to -15.33 itself.
In inequality notation, this is expressed as:
\[ x < -15.33 \]
The solution set includes all real numbers that are less than -15.33. In interval notation, this can be written as:
\[ (-\infty, -15.33) \]
Thus, the solution set for the inequality is all numbers less than -15.33, denoted by \((- \infty, -15.33)\).
