The third option, the arrow with the white circle(open circle) at -3 going left.

x < -3

Step-by-step explanation:

Since the white circlr or open circle means that something is greater than or less than. While a black circle or closed circle means that something is greater than and equal to or less than and equal to.

Given the inequality is: 3x < -9

3x < -9

÷3 ÷3

(only step is to divide by 3)

x < -3

This means that x is less than -3. or any value less than -3 to negative infinity.
