Answer:
The function would be 
.This is in the general form 
, where a is the initial value, b is the rate it increases by, and x is the amount of time.  For our function, the initial value is 4 and the rate it increases by is 2.
Step-by-step explanation:
 
        
                    
             
        
        
        
If you think about this equation as a line, then in order to have an infinite number of solutions is to have another equation that describes the same line.
So, for example 3y=2x-15 would be one of those.
        
                    
             
        
        
        
1.25j+5.25 would be the answer. just combine like terms
        
             
        
        
        
Dividing 3,724 by 6 would equal 620.66666666 repeating. Or 620.667
Hope this helped :) 
        
                    
             
        
        
        
Answer:
Carmen had the largest red to green apple ratio of 5 : 3
Step-by-step explanation:
Red apples : Green apples
Carmen = 20 red apples : 12 green apples
= 20 / 12
= 5 / 3 = 1.67
= 5 : 3
Dylan = 12 red apples : 10 green apples
= 12 / 10
= 6 / 5 = 1.2
= 6 : 5
Eli = 16 red apples : 20 green apples
= 16 / 20
= 4 / 5 = 0.8
= 4 : 5
Carmen had the largest red to green apple ratio of 5 : 3
