Which equation below and value for x fits this model? A)
2x = 30, x = 15

B)
2x = 6, x = 2

C)
2x = 6, x = 3

D)
x + x = 6, x = 1.5

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
