Solve the problem.The sum of three numbers is -2. If the second number is subtracted from the sum of the first and third numbers, the result is 4. If the third number is subtracted from the sum of the first and second numbers, the result is 6. Find the three numbers.[Hint: let x represent the first number, y the second number, and z the third number. Use the given conditions to write and solve a system of equations.]
A. x = 6, y = -2, z = -6 B. x = 6, y = -3, z = -5 C. x = 3, y = -1, z = -4 D. x = 5, y = -3, z = -4
Solve the problem.Find an equation of the line containing the centers of the two circles x2 + y2 + 6x + 4y + 12 = 0
and x2 + y2 - 2x + 10y + 22 = 0
A. -7x + 2y + 17 = 0 B. 3x - 4y + 17 = 0 C. 3x + 4y + 17 = 0 D. -3x + 4y + 17 = 0
