Which inequality represents the solution to 52x175 - 2x \geq 17?

A

x6x \leq -6

B

x6x \geq -6

C

x6x \leq 6

D

x6x \geq 6

Correct Answer: A

Choice A is the correct answer. Solving inequalities with negative coefficients requires reversing the inequality sign.

  1. Subtract 5: 52x51755 - 2x - 5 \geq 17 - 5, giving 2x12-2x \geq 12
  2. Divide by -2: 2x2122\frac{-2x}{-2} \leq \frac{12}{-2} (REVERSE the sign!)
  3. Simplify: x6x \leq -6

?�� Strategic Tip: Dividing by a negative number is the most common trap in linear inequalities. Always check the sign direction.

Choice B is incorrect because it fails to reverse the inequality sign when dividing by -2. Choice C is incorrect because it uses positive 6 instead of negative 6. Choice D is incorrect because it combines wrong sign and wrong direction.
