The correct Answer is:
To solve the problem, we need to find the maximum values of \( |x - 4| \) and \( |y + 4| \) given the constraints on \( x \) and \( y \). ### Step 1: Analyze the range of \( x \) We are given the inequality: \[ -2 \leq x \leq 3 \] This means \( x \) can take any value from \(-2\) to \(3\). ### Step 2: Transform the expression \( |x - 4| \) We can rewrite the expression \( |x - 4| \): \[ |x - 4| = |-(4 - x)| = |4 - x| \] Next, we need to find the maximum value of \( |x - 4| \) by considering the endpoints of the range of \( x \). ### Step 3: Calculate \( |x - 4| \) at the endpoints 1. When \( x = -2 \): \[ |x - 4| = |-2 - 4| = |-6| = 6 \] 2. When \( x = 3 \): \[ |x - 4| = |3 - 4| = |-1| = 1 \] ### Step 4: Determine the maximum value of \( |x - 4| \) From the calculations: - At \( x = -2 \), \( |x - 4| = 6 \) - At \( x = 3 \), \( |x - 4| = 1 \) Thus, the maximum value of \( |x - 4| \) is: \[ \text{Maximum value of } |x - 4| = 6 \] ### Step 5: Analyze the range of \( y \) We are given the inequality: \[ -3 \leq y \leq 2 \] This means \( y \) can take any value from \(-3\) to \(2\). ### Step 6: Transform the expression \( |y + 4| \) We can rewrite the expression \( |y + 4| \): \[ |y + 4| \] Next, we need to find the maximum value of \( |y + 4| \) by considering the endpoints of the range of \( y \). ### Step 7: Calculate \( |y + 4| \) at the endpoints 1. When \( y = -3 \): \[ |y + 4| = |-3 + 4| = |1| = 1 \] 2. When \( y = 2 \): \[ |y + 4| = |2 + 4| = |6| = 6 \] ### Step 8: Determine the maximum value of \( |y + 4| \) From the calculations: - At \( y = -3 \), \( |y + 4| = 1 \) - At \( y = 2 \), \( |y + 4| = 6 \) Thus, the maximum value of \( |y + 4| \) is: \[ \text{Maximum value of } |y + 4| = 6 \] ### Step 9: Compare the two quantities Now we compare the two quantities: - Quantity A: Maximum value of \( |x - 4| = 6 \) - Quantity B: Maximum value of \( |y + 4| = 6 \) Since both quantities are equal: \[ \text{Quantity A} = \text{Quantity B} \] ### Conclusion The two quantities are equal, so the answer is: \[ \text{Option 3: The two quantities are equal.} \]
