Question

Does anyone know the answer ?

Answer 1

a < - 13

The number line shows an open circle at negative 13 indicating that a cannot equal  negative 13. The arrow on the red section ( the solution ) is pointing to the left away from negative 13 indicating a has values less than - 13

a < - 13 is the inequality representing the solution

note if the circle was filled in this would indicate a is equal to negative 13
