Answer:
On the number line, put a closed circle on the -3 pointing to the left of the number line.
Explanation:
The formula to solve -3x + 3 ≥ 12 is to first subtract 3 from 12, therefore you are left with -3x ≥ 9. Since -3x is being "multiplied" by the x, you need to divide the -3 from the 9, which leaves you with X ≥ -3. The equation still has one more step to solving, you need to swap the sign to ≤. The rule states that you swap the sign if you divide or multiply by a negative number. Therefore, the solution is X ≤ -3. A closed circle represents an equation with ≤ or ≥. An open circle represents an equation with < or >. I am sorry that I am late. I hope this helps!
