Math Problem Statement

Solve the inequality and graph the solution on the line provided. minus, 9, plus, 6, x, is greater than or equal to, 39 −9+6x≥ 39

Solution

Let's solve the inequality step by step:

Given inequality:

9+6x39-9 + 6x \geq 39

Step 1: Add 9 to both sides to eliminate the constant term on the left-hand side:

9+6x+939+9-9 + 6x + 9 \geq 39 + 9 6x486x \geq 48

Step 2: Divide both sides by 6 to isolate xx:

x486x \geq \frac{48}{6} x8x \geq 8

Final solution:

x8x \geq 8

Graphing the solution:

To graph this inequality on a number line:

  1. Draw a number line and mark the point x=8x = 8.
  2. Since the inequality includes "greater than or equal to" ( \geq ), put a closed circle at x=8x = 8 to indicate that x=8x = 8 is included in the solution.
  3. Shade the line to the right of 8 to show that xx can take any value greater than or equal to 8.

Here are 5 related questions to further explore this concept:

  1. How would the graph change if the inequality were x>8x > 8 instead of x8x \geq 8?
  2. How would you solve an inequality like 5x12285x - 12 \leq 28?
  3. What is the difference between an open circle and a closed circle on a number line graph?
  4. Can inequalities have more than one solution? How would you graph that?
  5. How would you solve the inequality 3x+7>25-3x + 7 > 25?

Tip: Always remember that dividing or multiplying both sides of an inequality by a negative number reverses the inequality symbol.
