Which set of ordered pairs does not represent a function? O {(5,-2),(-6,-4), (-2,3), (-1,-4)}
O{(-3,4), (-8,0), (3,-8), (-3,-4)}
O {(6,3), (-1,5), (-7,3), (3,0)}
O {(3,9), (2,7), (9,9), (4, -3)}

The second choices is the answer

O{(-3,4), (-8,0), (3,-8), (-3,-4)} as you can see there's a repeating domain or value of x which is the -3

480 yds.

Step-by-step explanation:

Model is 12in X 24in

Scale is 1in = 4 yds

24 in is the length, so multiply the 24 and 4 to find length of the actual field.

24 *4 = 96 yds. Manny ran it 5 times, multiply 96 and 5.  96 * 5 = 480 yds.
