The correct Answer is:
To solve the given problem, we will analyze the two statements separately and find the values for \( x \) and \( y \). After that, we will compare the values to determine the relationship between them. ### Step-by-Step Solution: **Statement I: Solve the equation \( x^2 - 45x + 506 = 0 \)** 1. **Identify the coefficients**: The equation is in the standard form \( ax^2 + bx + c = 0 \), where \( a = 1 \), \( b = -45 \), and \( c = 506 \). 2. **Calculate the discriminant**: \[ D = b^2 - 4ac = (-45)^2 - 4 \cdot 1 \cdot 506 = 2025 - 2024 = 1 \] 3. **Find the roots using the quadratic formula**: The roots are given by: \[ x = \frac{-b \pm \sqrt{D}}{2a} = \frac{45 \pm 1}{2} \] 4. **Calculate the two possible values for \( x \)**: \[ x_1 = \frac{46}{2} = 23, \quad x_2 = \frac{44}{2} = 22 \] So, the values of \( x \) are \( 22 \) and \( 23 \). --- **Statement II: Solve the equation \( y^2 - 9y - 360 = 0 \)** 1. **Identify the coefficients**: The equation is in the standard form \( ay^2 + by + c = 0 \), where \( a = 1 \), \( b = -9 \), and \( c = -360 \). 2. **Calculate the discriminant**: \[ D = b^2 - 4ac = (-9)^2 - 4 \cdot 1 \cdot (-360) = 81 + 1440 = 1521 \] 3. **Find the roots using the quadratic formula**: The roots are given by: \[ y = \frac{-b \pm \sqrt{D}}{2a} = \frac{9 \pm \sqrt{1521}}{2} \] 4. **Calculate the two possible values for \( y \)**: First, find \( \sqrt{1521} = 39 \): \[ y_1 = \frac{9 + 39}{2} = 24, \quad y_2 = \frac{9 - 39}{2} = -15 \] So, the values of \( y \) are \( 24 \) and \( -15 \). --- ### Comparison of Values: Now we have: - Values of \( x \): \( 22 \) and \( 23 \) - Values of \( y \): \( 24 \) and \( -15 \) 1. **Compare \( x = 22 \) with \( y = 24 \)**: \[ 22 < 24 \quad \text{(True)} \] 2. **Compare \( x = 22 \) with \( y = -15 \)**: \[ 22 > -15 \quad \text{(True)} \] 3. **Compare \( x = 23 \) with \( y = 24 \)**: \[ 23 < 24 \quad \text{(True)} \] 4. **Compare \( x = 23 \) with \( y = -15 \)**: \[ 23 > -15 \quad \text{(True)} \] ### Conclusion: From the comparisons: - \( x \) is less than \( y \) when \( y = 24 \). - \( x \) is greater than \( y \) when \( y = -15 \). Since we have both \( x < y \) and \( x > y \), we conclude that **no relation can be established** between \( x \) and \( y \). ### Final Answer: The correct option is **D: No relation can be established**. ---
