Final answer:
P(x, y, z) represents x = y - z. P(3, 9, 6) = 3, P(2, 10, 7) = 3, P(0, 10, 10) = 0.
Step-by-step explanation:
P(x, y, z) denotes x = y - z. The domains for x, y, and z are the positive integers. To evaluate P(3, 9, 6), substitute these values into the equation: P(3, 9, 6) = 3 = 9 - 6 = 3. Therefore, P(3, 9, 6) is equal to 3. Similarly, to evaluate P(2, 10, 7), substitute the values: P(2, 10, 7) = 2 = 10 - 7 = 3. Therefore, P(2, 10, 7) is equal to 3. Finally, to evaluate P(0, 10, 10), substitute the values: P(0, 10, 10) = 0 = 10 - 10 = 0. Therefore, P(0, 10, 10) is equal to 0.
