The correct Answer is:
To solve the given equations step by step, let's start with each equation separately. ### Step 1: Solve Equation I: \(6x^2 - 19x + 15 = 0\) 1. **Identify the coefficients**: - \(a = 6\), \(b = -19\), \(c = 15\) 2. **Use the quadratic formula**: The quadratic formula is given by: \[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] 3. **Calculate the discriminant**: \[ b^2 - 4ac = (-19)^2 - 4 \cdot 6 \cdot 15 = 361 - 360 = 1 \] 4. **Substitute values into the formula**: \[ x = \frac{-(-19) \pm \sqrt{1}}{2 \cdot 6} = \frac{19 \pm 1}{12} \] 5. **Calculate the two possible values for \(x\)**: - \(x_1 = \frac{20}{12} = \frac{5}{3}\) - \(x_2 = \frac{18}{12} = \frac{3}{2}\) ### Step 2: Solve Equation II: \(5y^2 - 22y + 24 = 0\) 1. **Identify the coefficients**: - \(a = 5\), \(b = -22\), \(c = 24\) 2. **Use the quadratic formula**: \[ y = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] 3. **Calculate the discriminant**: \[ b^2 - 4ac = (-22)^2 - 4 \cdot 5 \cdot 24 = 484 - 480 = 4 \] 4. **Substitute values into the formula**: \[ y = \frac{-(-22) \pm \sqrt{4}}{2 \cdot 5} = \frac{22 \pm 2}{10} \] 5. **Calculate the two possible values for \(y\)**: - \(y_1 = \frac{24}{10} = \frac{12}{5}\) - \(y_2 = \frac{20}{10} = 2\) ### Step 3: Compare the values of \(x\) and \(y\) From the solutions: - \(x_1 = \frac{5}{3} \approx 1.67\) - \(x_2 = \frac{3}{2} = 1.5\) - \(y_1 = \frac{12}{5} = 2.4\) - \(y_2 = 2\) ### Step 4: Determine the relationship between \(x\) and \(y\) - For \(x_1\) and \(y_1\): - \(x_1 \approx 1.67 < y_1 = 2.4\) - For \(x_2\) and \(y_2\): - \(x_2 = 1.5 < y_2 = 2\) In both cases, \(x < y\). ### Conclusion The relationship is \(x < y\).
