Which set of ordered pairs shows a function? O A. {(2, 3), (2, 6), (2, 9). (2, 12), (2, 15) }
O B. {(2, 6), (-3,6), (-8, 11), (6, 2) (9,-7))
O c. {(3, -5), (4, -4), (5,-3), (4, -2). (3, -1)}
O D. {(3, 8), (-3,2), (-6,0), (-3, -2), (3,-8)}

B, hope this helps!

Step-by-step explanation:

Functions can not have repeating X values.

O B. {(2, 6), (-3,6), (-8,11), (6, 2) (9,-7)}

Step-by-step explanation:

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
