Answer:
-5/8
Step-by-step explanation:
First find the least common denominator. It is 8.
1/8- 2/8- 4/8
 
        
                    
             
        
        
        
Answer:(x-1)(x+8) 
Step-by-step explanation: You need to set it up as (x+y)(x+z) format. To get that you need to flip the zeroes making them the opposite. So the answer in this case would be (x-1)(x+8).
 
        
             
        
        
        
The correct answer is:  [A]:  " <span>x(y – 5) = 2 " .
</span>_____________________________________________________
Consider:
_____________________________________________________
Choice:  [A]:  " x(y–5) = 2 " ; 
Divide each side by "x" ;
" [x(y – 5)] / x  = 2/x " ; 
  →  y – 5 = 2/x  ;
Add "5" to each side of the equation:
y – 5 + 5 = 2/x + 5 ;
  →  y = 2/x + 5  ;  not a line;  since one cannot divide by "zero" ; there would be no "point" on the graph at "x = 0".  So, this answer choice:  [A] is correct.

Choice [B]:
 
y -2x -18 = 0 
y - 2x = 18
y = 18 + 2x ;  y = 2x + 18 ; is a line.

Choice C)  3y + 12 - 6x = 5 ; 
3y = 5 - 12 + 6x ; 
3y = -7 + 6x ;  3y = 6x - 7 ;  y = 6x/3 - 7/3 ;  y = 2x - 7/3 ;  is a line.

Choice:  [D]:
2(y+x) = 0 ;
[2*(y+x)] / 2 = 0/2 ;  y + x = 0 ;  y = -x ;  is a line.
