In the square BX + CZ of equation y = ax, when x = 1, y = 0. When x = - 1, y = - 2. When x = 2, y = 8. Find the value of ABC The sum of ABC three numbers is 18. Given that a is 1 more than B, and the sum of B and C is 4 more than a, then what are ABC respectively
Take x = - 1, y = 4 into the square of y = ax + BX + C, and get: 4 = A-B + C, which is Formula 1. Take x = 2, y = 4 into the square of y = ax + BX + C, and get: 4 = 4A + 2B + C, which is formula 2. Take x = 1, y = 2 into the square of y = ax + BX + C, and get: 2 = a + B + C, which is Formula 1, 2, 3
