Answer:
I believe it is the second answer;
F(x)= (1/2)(2)^x
Step-by-step explanation:
1. the initial value is 0.5, so the first number will have to be 1/2, and it is increasing so the value of <em>b</em> must be above 1. 
2. Through process of elimination, you can determine that the second equation matches the graph.

Length (L): 2w + 3
width (w): w
border (b): 
Area (A) = (L + b) * (w + b)   <em>NOTE: This is assuming the width also has a border</em>
               = (2w + 3 +  ) * (w +
) * (w +  )

Parallel lines as they are in the same plane but never meet.
        
             
        
        
        
Answer:
Step-by-step explanation:
3) Sales tax rate = 
                          = 8.50 
                         = 9%
4) Rate of commission = 
                                      = 5 %
5) Reduction = 
                     =$ 1500
New price = 5000 - 1500
                = $ 3500
 
        
             
        
        
        
Answer: 10
use (PEMDAS)
P parentheses ()
E exponents 
M multiplication • , () , x
D division
A addition +
S subtraction -
Explanation:
There are no parentheses.
There are exponents. 
The multiplication is the exponents.
There is division.
There is addition and subtraction.
-how to solve-
First, do 2 to the second power and get 4.
Next, do 12-2+4 divided by 8.
Next do multiplication: there’s no more.
Next do division: you can’t do 4 divided by 8 so instead, do 12-2 = 10 plus 8. 
Hope this helps!
