Solve the inequality 6x+9>57

Question

. Which of the following graphs shows the solution?(1 point)
Responses

A number line is shown ranging from negative 2 to 18 with numbers listed in unit increments. An open point is plotted on the number line at 8. A leftward arrow is marked on the number line that originates at the open point and goes beyond negative 2.

Answer 1

To solve the inequality \(6x + 9 > 57\), we'll start by isolating \(x\).

1. Subtract 9 from both sides: \[ 6x > 57 - 9 \] \[ 6x > 48 \]

2. Now divide both sides by 6: \[ x > \frac{48}{6} \] \[ x > 8 \]

The solution to the inequality is \(x > 8\).

Now, let's evaluate the given graph options based on this solution:

• The correct graph should have an open point at 8 and an arrow extending to the right, indicating that all values greater than 8 are included in the solution.

From the options you provided, the correct graph is:

• A number line is shown ranging from negative 2 to 18 with numbers listed in unit increments. An open point is plotted on the number line at 8. A rightward arrow is marked on the number line that originates at the open point and goes beyond 18.

This matches the solution we found: \(x > 8\).
