Answer:
   There are no real solutions. The complex solutions are ...
   (x, y) = (2.5-i√1.75, -2.5+i√1.75)  or  (2.5+i1.75, -2.5-i1.75)
Step-by-step explanation:
Subtract the first equation from the second.
   y -y = (x^2 -6x +8) -(-x)
   0 = x^2 -5x +8
Rewrite to facilitate completing the square:
   x^2 -5x = -8
   x^2 -5x +6.25 = -1.75 . . . . . add 6.25 to complete the square
   (x -2.5)^2 = -1.75 . . . . . write as a square
   x -2.5 = ±i√1.75 . . . . . . take the square root
   x = 2.5 ± i√1.75 . . . . . . add 2.5; y is the opposite of this
Solutions are ...
- x = 2.5 +i√1.75, y = -2.5 -i√1.75
- x = 2.5 -i√1.75, y = -2.5 +i√1.75
_____
The graph shows the equations have no point of intersection, meaning there are no real solutions. The complex solutions are shown above.
 
        
             
        
        
        
It would be: {(–5, 3), (–7, 5), (–9, 6), (–12, 10), (–16, 12)}

The answer is 3 and you have to subsitute -6 in for n to get your answer
        
             
        
        
        
(26/25) x (15/28) x (8/39)
Divide top and bottom by 3 :
(26/25) x (5/28) x (8/13)
Divide top and bottom by 5 :
(26/5) x (1/28) x (8/13)
Divide top and bottom by 4 :
(26/5) x (1/7) x (2/13)
= 52 / 455 = 0.11429... (rounded)
