Answer: 2/3
(7/9) (18/21)
(7/9) (6/7)
common factor is 3 between 18 and 21. 7 x 3 = 21 and 6 x 3 = 18
7/9 6/7 multiply 7 x 9 = 63 and 6 x 7 = 42
= 42/63
= 2/3
decimal: 0.666667
the equation would be x-12=20.
the solution would be x=8.
Answer:
Step-by-step explanation:
6: 6, 12, 18, 24, 30, 36, 42, 48, 54
14: 14, 28, 42, 56
the LCM (least common multiple) is 42.
{(3, -1), (7, 1), (-6, -1), (9, 1), (2, -1)}
Any relation having repetitive x-coordinates, is NOT a function.
x = −1
