1. Problem Description

The problem asks to find the number line that represents the solution to the inequality 3x+719-3x + 7 \ge 19.

2. Solution Steps

First, we need to solve the inequality for xx.
3x+719-3x + 7 \ge 19
Subtract 7 from both sides:
3x+77197-3x + 7 - 7 \ge 19 - 7
3x12-3x \ge 12
Divide both sides by -

3. Since we are dividing by a negative number, we need to flip the inequality sign:

3x3123\frac{-3x}{-3} \le \frac{12}{-3}
x4x \le -4
Now we need to find the number line that represents x4x \le -4. This means we need a closed circle (or solid dot) at -4, and the line should extend to the left (towards negative infinity).
Looking at the options, the second number line has a closed circle at -4, and the arrow extends to the left.

3. Final Answer

The second number line shows the solution to the inequality.
