Which of the following lines has a slope of -1/2? x + 2y = 0; x - 2y = 0; -x + 2y = 0

If x = 12 and y = 3, what is the value of x - y 2? 81 6 3 18

After the seventh month of a 12-month loan: the numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)} = , and the denominator is: {(n) + (n + 1) + + (n + 11)} = . therefore, the fraction is numerator/denominator (to the nearest tenth) = %

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
