Answer

The correct graph would be a number line with an open circle at 15 and shading to the right.

Steps

Step 1 :Subtract 2x from both sides of the inequality: \(3x - 2x > 2x + 9 - 2x\) which simplifies to \(x > 2x + 9\).

Step 2 :Add 6 to both sides of the inequality: \(x + 6 > 2x + 9 + 6\) which simplifies to \(x > 15\).

Step 3 :The solution to the inequality is \(\boxed{x > 15}\). This means that any number greater than 15 is a solution to the inequality.

Step 4 :The correct graph would be a number line with an open circle at 15 and shading to the right.
