Answer: First option.
Step-by-step explanation:
 You know that the function represented by the equation is the following:
 
 Then, you can follow these steps in order write the equation in function notation with "x" as the independent variable:
 1. Solve for "y":
 Add  to both sides:
 to both sides:
 
 Add 9 to both sides:
 
 2. Since  is a common way of representing "y", you get:
 is a common way of representing "y", you get:
 
 
 
 
        
                    
             
        
        
        
 Answer:
if the question is 4 + 4 = y - 1 than y = 9 otherwise you might want to rewrite the equation.
 
        
                    
             
        
        
        
Answer:

C is correct. 
Step-by-step explanation:
At a picnic, 
Number of adults is 3 times as number of children. 
Number of women is twice as number of men. 
Total number of men, women and children at the picnic be x
Let number of children be c
Let number of men be m 
Let number of women be w
# Number of women is twice as number of men, w = 2m 
# Number of adults is 3 times as number of children, w + m = 3c
       2m + m = 3c     (∴  w=2m )
                 c = m
Total number of men, women and children at the picnic be x
∵       c + m + w = x
      m + m + 2m = x
                     4m = x
Number of men, 
Hence, The total number of men will be  
 
        
             
        
        
        
Answer:
5.6
Step-by-step explanation:
3.4-2.3=1.1
2.3+1.1=3.4
3.4+1.1=4.5
4.5+1.1=5.6
