YES: These points represent a function because none of the vertical lines I drew passed through more than one point.
        
                    
             
        
        
        
Multiple-3(x+0.6) and 6(x+2.4) you will get -3x-1.8=6x+14.4 then you add -3x + 6x you will get -9x=14.4+1.8 you add 14.4+1.8 that will give you 16.2 then divide that by -9
 
        
        
        
Answer:
B
Step-by-step explanation:
Using the exact values
cos150° = - cos30° = - 
sin150° = sin30° = 
Given
z = 4(cos150° + isin150° ) , substitute values
   = 4(-  +
 +   i )
i ) 
   = - 2 + 2i , that is
 + 2i , that is
(- 2 , 2 ) → B
, 2 ) → B
