Answer:
(6 - 5x(2))(x(4) - x(3)) 
(6 - 5x^2) (x^4 - x^3) 
6x^4 - 6x^3 - 5x^6 + 5x^5 
-5x^6 + 5x^5 + 6x^4 - 6x^3 
Step-by-step explanation:
 
        
                    
             
        
        
        
Answer:
The midpoint of the segment is (-0.5,0.5).
Step-by-step explanation:
Midpoint of a segment:
The midpoint of a segment is given by the mean of its coordinates.
Segment with end points (4,2),(-5,-1)
x-coordinates: 4 and -5
y-coordinates: 2 and -1
x-coordinate of the midpoint:

y-coordinate of the midpoint:

The midpoint of the segment is (-0.5,0.5).
 
        
             
        
        
        
Y= -x and y= -1/x
Are one-one
y= -x, inverse x= -y
Identify function
hence, inverse of y= -x in y= -x
similarly in the case of y= -1/x
so option (D) I and II, only
        
             
        
        
        
These three vectors are linearly <u>dependent</u> (details are in the attachment).
