The correct Answer is:
To solve the problem step-by-step, we start with the given information and analyze the options provided. ### Step 1: Understand the Given Information We know that: - \( x \geq y \) (which means \( x \) is greater than or equal to \( y \)) - \( b > 0 \) (which means \( b \) is a positive real number) ### Step 2: Analyze the Options We have four options to evaluate: - Option A: \( \frac{x}{b} \geq \frac{y}{b} \) - Option B: \( \frac{x}{b} > \frac{y}{b} \) - Option C: \( \frac{x}{b} \leq \frac{y}{b} \) - Option D: \( \frac{x}{b} < \frac{y}{b} \) ### Step 3: Dividing by a Positive Number Since \( b > 0 \), we can divide both sides of the inequality \( x \geq y \) by \( b \) without changing the direction of the inequality. So, we divide: \[ \frac{x}{b} \geq \frac{y}{b} \] ### Step 4: Conclusion From the above step, we conclude that: - The statement \( \frac{x}{b} \geq \frac{y}{b} \) holds true. Thus, the correct option is **Option A**: \( \frac{x}{b} \geq \frac{y}{b} \). ### Step 5: Eliminate Other Options - **Option B**: \( \frac{x}{b} > \frac{y}{b} \) cannot be concluded since \( x \) could be equal to \( y \). - **Option C**: \( \frac{x}{b} \leq \frac{y}{b} \) is incorrect as it contradicts our conclusion. - **Option D**: \( \frac{x}{b} < \frac{y}{b} \) is also incorrect for the same reason. ### Final Answer The final answer is **Option A**: \( \frac{x}{b} \geq \frac{y}{b} \). ---
