Which set of ordered pairs does NOT represent y as a function of x?
A) {(1, 2), (1, 3), (1, 1)}
B) {(1, 1), (2, 2), (-2, 3)}
C) {(1, 2), (2, 3), (3, 3)}
D). {(1, 1), (2, 1), (3, 1)}

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
