The correct Answer is:
To solve the given equations and find the relationship between the variables \(x\) and \(y\), we will follow these steps: ### Step 1: Solve Equation I The first equation is: \[ x^2 - 2x - 24 = 0 \] To solve this quadratic equation, we can factor it. We need two numbers that multiply to \(-24\) (the constant term) and add up to \(-2\) (the coefficient of \(x\)). The numbers that satisfy these conditions are \(6\) and \(-4\) because: \[ 6 \times (-4) = -24 \quad \text{and} \quad 6 + (-4) = 2 \] Now we can rewrite the equation: \[ x^2 - 6x + 4x - 24 = 0 \] Grouping the terms: \[ (x - 6)(x + 4) = 0 \] Setting each factor to zero gives us: \[ x - 6 = 0 \quad \Rightarrow \quad x = 6 \] \[ x + 4 = 0 \quad \Rightarrow \quad x = -4 \] So, the solutions for \(x\) are: \[ x = 6 \quad \text{or} \quad x = -4 \] ### Step 2: Solve Equation II The second equation is: \[ y^2 + 3y - 40 = 0 \] Again, we will factor this quadratic equation. We need two numbers that multiply to \(-40\) (the constant term) and add up to \(3\) (the coefficient of \(y\)). The numbers that satisfy these conditions are \(8\) and \(-5\) because: \[ 8 \times (-5) = -40 \quad \text{and} \quad 8 + (-5) = 3 \] Now we can rewrite the equation: \[ y^2 + 8y - 5y - 40 = 0 \] Grouping the terms: \[ (y + 8)(y - 5) = 0 \] Setting each factor to zero gives us: \[ y + 8 = 0 \quad \Rightarrow \quad y = -8 \] \[ y - 5 = 0 \quad \Rightarrow \quad y = 5 \] So, the solutions for \(y\) are: \[ y = -8 \quad \text{or} \quad y = 5 \] ### Step 3: Compare the Values Now we have the values for \(x\) and \(y\): - \(x = 6\) or \(x = -4\) - \(y = -8\) or \(y = 5\) We need to compare these values: 1. If \(x = 6\): - Compare with \(y = -8\): \(6 > -8\) - Compare with \(y = 5\): \(6 > 5\) 2. If \(x = -4\): - Compare with \(y = -8\): \(-4 > -8\) - Compare with \(y = 5\): \(-4 < 5\) ### Conclusion From the comparisons, we can see: - When \(x = 6\), \(x\) is greater than both values of \(y\). - When \(x = -4\), \(x\) is greater than \(y = -8\) but less than \(y = 5\). Thus, we cannot establish a consistent relationship between \(x\) and \(y\) as it varies based on the values chosen. Therefore, the answer is: **No relation can be established between \(x\) and \(y\).**
