8/9 = 0,8
0,8/4 = 0,2 
so each piece was 0,2 yard long 
        
             
        
        
        
N*x*a=n+x+a

12.
It is easy all you have to do is 15-3 because 1+2=3
        
             
        
        
        
Answer: OPTION C.
Step-by-step explanation:
 The equation of the line in Slope-Intercept form is:
 
 Where "m" is the slope and "b" is the y-intercept.
 Notice that the line of f(x) is dashed. This means that the symbol of the inequality must be  or
 or  .
. 
 Since the shaded region A is above the line, the symbol is 
 Observe that its y-intercept is:
 
 
 The line of g(x) is solid. This means that the symbol of the inequality must be  or
 or  .
.
 Since the shaded region B is below the line, the symbol is .
 .
 Observe that its y-intercept is:
  .
.
 
 Based on this, we can conclude that the graph represents the following System of Inequalities:
