Answer:
A and B are parallel to D and C
or
A and D to B and C 
basically do a line and expand them if they touch they are not parralelogram but if they don't they are 
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1)   ....   x_1 = 3 and y_1 = - 1
m is the slope to  x - 3y = 9 because (lines are  parallel )
calculate : m   by equation   x - 3y = 9 : 
x = 3y +9
divid by : 3      1/3 x = y + 3
y =  (1/3) x - 3      so : m = 1/3
an equation parallel to x - 3y = 9 that passes through the point ( 3, -1 ) is : 
y +1 = (1/3)(x - 3)
 
        
             
        
        
        
Answer:
362880
Step-by-step explanation:
You have to subtract the two people who are already doing something in line so you would do 11-2 which equals 9. Then you would do 9 mPr 9 which gives you an answer of 362,880.
 
        
             
        
        
        
2:15
Half an hour is 30 minutes
A quarter is 15 minutes
A quarter to 3 is 2:45
Half an hour before 2:45 is 2:15
