Answer

The solution to the inequality is \( x < 3 \). To graph it, draw a number line, place an open circle at 3, and shade the area to the left of 3.

Solution

1. Start with the inequality: \[ -6x > -18 \] 2. Divide both sides by \(-6\). Remember that when dividing or multiplying an inequality by a negative number, the inequality sign reverses: \[ x < \frac{-18}{-6} \] 3. Simplify the fraction: \[ x < 3 \] 4. The solution to the inequality is: \[ x < 3 \] 5. To graph the solution set on a number line: - Draw a horizontal line. - Mark the point \(3\) and use an open circle at \(3\) to indicate that \(3\) is not included in the solution. - Shade the portion of the line to the left of \(3\) to represent all values less than \(3\).

To solve the inequality \(-6x > -18\), you first need to isolate \(x\). Start by dividing both sides by -6. Remember, when you divide or multiply by a negative number, you must flip the inequality sign. So, you get \(x < 3\). Now, to graph the solution set on a number line, you would place an open circle at 3 (indicating that 3 is not included in the solution) and shade everything to the left of 3, showing all numbers less than 3 are included in the solution set. Happy graphing! In everyday life, this inequality could represent scenarios like budgets where you can spend less than a certain amount (3 in this case) but not equal to it. For instance, if you're planning on buying snacks with only $3 in hand, any purchase that leaves you with less than that is fair game but not exactly hitting the mark!
