Which set of ordered pairs represents a function? Please Help A. {(-1.5, 3), (-2.5, 3), (0, 3), (3.5, 3)}
B. {(2, 12), (6, 15), (-2, -1), (6, 3), (8, 8)}
C. {(7, 1), (7, -1), (5, 2), (5, -2), (3, 3)}
D. {(1.2, 3), (2.2, 4), (3.2, 5), (3.2, 6)}

how am i supposed to answer

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
