Answer:
The numbers are 39 and 14.
Step-by-step explanation:
Equation 1, sum of the numbers:
  
x  +  y   =  53
  
Equation 2, difference of the numbers:
  
x  -  y  = 25
  
System of equations:
  
x  +  y  =  53
x  -  y   =  25
----------------
2x = 78
  
x = 39
  
Solve for y:
  
39  +  y  = 53
  
y  =  14
  
The numbers are 39 and 14.
 
        
             
        
        
        
C = Total Daily Cost
Total Daily Cost = (Salary per employee per day)×(Total no. of employees on that day) + Fixed Expenses.
C = 35x + 100
        
                    
             
        
        
        
Answer:
x^2 + 10x + 25
Step-by-step explanation:
(B/2) ^2
10/2 = 5 
5^2 = 25 
 
        
             
        
        
        
Y = a(b^x)
y=mx + b is the equation of a line. It is a linear function because it has a constant rate of change. 
y = a(b^x) is an exponential function because it has has an exponent and its rate of change is not constant
        
             
        
        
        
Answer:
d. 7 × (10 + 9) = (7 × 10) + (7 × 9)
Step-by-step explanation:
The format of writing numbers in distributive property is a(b+c) = (a×b)+(a×c)
We can see that in choice d. 7 × (10 + 9) = (7 × 10) + (7 × 9) it is in correct format of writing numbers in distributive property. Thus, choice d. is correct.
Verification:-
a(b+c) = (a×b)+(a×c)
7 × (10 + 9) = (7 × 10) + (7 × 9)
