Which set of ordered pairs is not a function? A)(2, 3),(4,9), (3, 8), (4, 15)
B) (-9, 4), (-6, 3), (-2, 8), (0, 21)
C) (1, 2), (3,5), (6,9), (7, 11)​

Its A

Step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
