The correct Answer is:
To solve the given equations step by step, we will start with the first equation and then move on to the second equation. ### Step 1: Solve the first equation \(x^2 - 21x + 38 = 0\) 1. **Identify the coefficients**: The equation is in the standard quadratic form \(ax^2 + bx + c = 0\) where: - \(a = 1\) - \(b = -21\) - \(c = 38\) 2. **Factor the equation**: We need to find two numbers that multiply to \(c\) (which is \(38\)) and add up to \(b\) (which is \(-21\)). The factors of \(38\) that satisfy this condition are \(-19\) and \(-2\). 3. **Rewrite the equation**: We can express the equation as: \[ (x - 19)(x - 2) = 0 \] 4. **Set each factor to zero**: - \(x - 19 = 0 \Rightarrow x = 19\) - \(x - 2 = 0 \Rightarrow x = 2\) Thus, the solutions for \(x\) are \(x = 19\) and \(x = 2\). ### Step 2: Solve the second equation \(y^2 - 11y + 28 = 0\) 1. **Identify the coefficients**: The equation is also in the standard quadratic form where: - \(a = 1\) - \(b = -11\) - \(c = 28\) 2. **Factor the equation**: We need to find two numbers that multiply to \(c\) (which is \(28\)) and add up to \(b\) (which is \(-11\)). The factors of \(28\) that satisfy this condition are \(-7\) and \(-4\). 3. **Rewrite the equation**: We can express the equation as: \[ (y - 7)(y - 4) = 0 \] 4. **Set each factor to zero**: - \(y - 7 = 0 \Rightarrow y = 7\) - \(y - 4 = 0 \Rightarrow y = 4\) Thus, the solutions for \(y\) are \(y = 7\) and \(y = 4\). ### Step 3: Compare the values of \(x\) and \(y\) We have the following pairs of values: - \(x = 2\) and \(y = 4\) - \(x = 2\) and \(y = 7\) - \(x = 19\) and \(y = 4\) - \(x = 19\) and \(y = 7\) Now we will compare the values: 1. For \(x = 2\) and \(y = 4\): \(2 < 4\) (so \(x < y\)) 2. For \(x = 2\) and \(y = 7\): \(2 < 7\) (so \(x < y\)) 3. For \(x = 19\) and \(y = 4\): \(19 > 4\) (so \(x > y\)) 4. For \(x = 19\) and \(y = 7\): \(19 > 7\) (so \(x > y\)) ### Conclusion: Since \(x\) can be both less than \(y\) and greater than \(y\) depending on the values chosen, we cannot establish a consistent relationship between \(x\) and \(y\). Therefore, the final answer is that the relationship cannot be established.
