Answer:
I used my calculator and it says c=16n-t+2b
 
        
             
        
        
        
Answer:
x = 60
Step-by-step explanation:
The tip of the triangle's angle is 100 (b/c 180-80)
x + 100 + 20 = 180
x + 120 = 180
x = 60
 
        
                    
             
        
        
        
Answer:
f'(x)
Step-by-step explanation:
The derivative of the function:

The rule for the product of two functions:
f'(x)
Therefore 
g(x)
g'(x)
f(x)
f'(x)
f'(x)
 
        
             
        
        
        
For this case we have the following situation:
 The monthly cost of a gym in the city is $ 3. The initial registration is $ 25. Write a mathematical expression that models the problem.
 So we have to define variables:
 x: number of months
 y: total cost
 The mathematical expression that models the problem is:
