Answer:
k=6,912
Step-by-step explanation:
5678+1234=6912
 
        
                    
             
        
        
        
C(t)= -0.3t^2 + 7.2t - 3.2 
12c = 40
        
             
        
        
        
So,...
the slope intercept form is y = mx+b
  the m is the slope, and the b is the coordinate that intercepts the y-axis
so to start you off, 4x - 9y = 2
4x - 9y = 2
-4x            - 4y
-9y = -4y +2
divide both sides by -9
<u>-9y </u>= <u>-4y + 2</u>
 -9          -9
y = 4/9 x - 2/9
