Answer:
A) 2
Step-by-step explanation:
Start off with the given information. The question states that the x-int. is 4, so you should recognize that there is a point at (4,0). Plug the point into the equation.
k(4) + 2(0) + 8 = 0
Now simplify the equation.
4k + 0 + 8 = 0
Isolate the variable, make sure it's on its own side.
4k = 8
Now get the k by itself to solve the equation. Divide both sides by 4.
k = 2
 
        
             
        
        
        
The answer is 6/14 , this should be correct because it has 14 sections which makes it smaller than the rest!
        
             
        
        
        
Slope = (y2 - y1)/(x2 - x1)
Slope = (8 - 0)/(3 - 1)
Slope = 8/2
Slope = 4
Answer
4
 
        
                    
             
        
        
        
270 degrees this because when you count each angle it is 90 degrees then 180 degrees then 270 
        
                    
             
        
        
        
C- charge
H- hours
D- diagnostic fee
C= #H(90)+ D
C= 4.6(90)+50
 =414+50
 =$464
C-$800
H-?
D-50
C= #H(90)+50
800=H(90)+50
H(90)=800-50
H(90)=750
H(90)/90=750/90
H=750/90
H= 8.33333333
