So (7.4*105)-(8.9*103)   (The sum of all departments)-(The sum of the accounting department) 
(7.4*105)-(8.9*103) = (777)-(916.7) =(-139.7), not sure, did you write the problem wrong? If the total of the company is less than what the account dept used, something is off.  
        
             
        
        
        
Answer:
B
Step-by-step explanation:
 
        
                    
             
        
        
        
Perimeter = sum of all sides
32 = 2(x+2) + 2(7)
32 = 2x+4 + 14
32 = 2x+18
14 = 2x
 /2     /2
7 = x
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
cuz it has a variable by it
 
        
             
        
        
        
I assume by starting value, you mean y-intercept. The y-intercept is 15
To find this, we need to use slope intercept form and the given information to find it. 
y = mx + b ----> plug in the known values
9 = -3/4(8) + b
9 = -6 + b
15 = b
Therefore, the starting value is 15.
