Solve both equations and choose the correct relationship between x and y.I. \( 2x^2 - 11x + 15 = 0 \)II. \( 3y^2 - 8y + 4 = 0 \) Answer: A. x > y Answer: (A) x > y I gives x = 2.5, 3. II gives y = 0.67, 2. Comparing every pair of values: x > y. 1
- In the following question, two equations numbered I and II are given. Solve both equations and choose the correct relationship between x and y.I. \( x^2 - 4x + 4 = 0 \)II. \( y^2 - 5y + 6 = 0 \) Answer: C. x ≤ y Answer: (C) x ≤ y I gives x = 2. II gives y = 2, 3. Comparing every pair of values: x ≤ y. 1
- In the following question, two equations numbered I and II are given. Solve both equations and choose the correct relationship between x and y.I. \( x^2 + 11x + 30 = 0 \)II. \( y^2 + 13y + 42 = 0 \) Answer: B. x ≥ y Answer: (B) x ≥ y I gives x = -6, -5. II gives y = -7, -6. Comparing every pair of values: x ≥ y. 1
- In the following question, two equations numbered I and II are given. Solve both equations and choose the correct relationship between x and y.I. \( x^2 - 9x + 20 = 0 \)II. \( y^2 - 15y + 56 = 0 \) Answer: B. x < y Answer: (B) x < y I gives x = 4, 5. II gives y = 7, 8. Comparing every pair of values: x < y. 1
- In the following question, two equations numbered I and II are given. Solve both equations and choose the correct relationship between x and y.I. \( x^2 + 3x - 28 = 0 \)II. \( y^2 - 2y - 15 = 0 \) Answer: D. x = y or the relationship between x and y cannot be established Answer: (D) x = y or the relationship between x and y cannot be e... 1
- In the following question, two equations numbered I and II are given. Solve both equations and choose the correct relationship between x and y.I. \( x^2 - 11x + 30 = 0 \)II. \( y^2 - 7y + 12 = 0 \) Answer: A. x > y Answer: (A) x > y I gives x = 5, 6. II gives y = 3, 4. Comparing every pair of values: x > y. 1
