Answer:
1st option
Step-by-step explanation:
to find f(g(x)) substitute x = g(x) into f(x) , that is
f(g(x))
= f(4x - 5)
= 2(4x - 5) + 1 ← distribute parenthesis
= 8x - 10 + 1
= 8x - 9
 
        
             
        
        
        
Discount prices/the discount 
E.g.the new price of the book is 75 which has a discount of 75%
The original price = 75/0.75=100
        
             
        
        
        
Answer:
The number of subscribers in 2008 is 110,845,988
Step-by-step explanation:
The number of cell phone subscribers in Arlington, in t years after 1985, can be modeled by the following equation.

And which N(0) is the number of subscribers in 1985 and r is the rate it increases per year, as a decimal.
In 1985, there were 285 cell phone subscribers in Arlington.
This means that 
The number of subscribers increased by 75% per year since 1985. 
This means that 
So

Find the number of subscribers in 2008. 
2008 is 2008-1985 = 23 years after 1985. So we have to find N(23).

The number of subscribers in 2008 is 110,845,988
