tis always a good idea when factoring to start off with a quick prime factoring.

 
        
             
        
        
        
-x^2 + 9 - 3x^2 - 11x + 4
-4x^2 - 11x + 13
        
             
        
        
        
Answer:
6/9 = 2/3
Step-by-step explanation:
1/3 = 3/9
3/9 = 3/9
3/9 + 3/9= 6/9 = 2/3
 
        
                    
             
        
        
        
Answer:
(0, 11) is a solution.
(8, 12)  is a solution.
(16, 13) is a solution
(1, 89/8)   
(2,  45/4)
Step-by-step explanation:
y = 1/8x + 11
for this equation....
y = (1/8) x + 11
let x = 0  get
y = 0 + 11 = 11
(0, 11) is a solution.
(8, 12)  is a solution.
(16, 13) is a solution
(1, 89/8)   because    y = 1/8 + 11 = 1/8 + 88/8 = 89/8 
(2,  45/4)
