Math Problem Statement

Solve for x and graph the solution on the number line: -3 ≥ x / -2

Solution

To solve the inequality 3x2-3 \geq \frac{x}{-2}:

  1. Start by isolating xx by eliminating the fraction. Multiply both sides by 2-2. Remember, when multiplying or dividing by a negative number in inequalities, the inequality sign flips.

    3×2x-3 \times -2 \leq x

  2. Simplify:

    6x6 \leq x

  3. This can be written as:

    x6x \geq 6

Answer in Inequality Notation:

The solution is: x6x \geq 6

Graphing the Solution on a Number Line:

To graph x6x \geq 6:

  • Draw a number line.
  • Place a closed dot at 66 to indicate that 66 is included in the solution.
  • Shade the line to the right of 66 to represent all values greater than or equal to 66.
