Determine whether each of the following points is a solution to the given system. Justify your answer. a) (-10,-1) y= 1/2x+4, y=4x+30
b) (2, 3/2) y= 8-x/4, y= 5/4x-1

Determine if the equation defines y as a function of x: 2xy = 1. yes o no

Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m? -15m = -4m -7m - 8 = m - 4 -3m - 8 = 4 - m m - 4 = -7m - 8 -8 - 7m = -4 + m -8 - 3m = 4 - m
