G(F(2)) 
So f would be x 
-(2x+1)-2 you slove it and get you answer and plug the answer back into the equation above as x 
-(2(answer)+1)-2 
Hope this helps
        
             
        
        
        
Answer: 18 and 32
Step-by-step explanation: The first thing you want to do is create a system of equations.
Let's use x to represent one number and y to represent the other.
So, we know that x+y=50 and x-y=14.
We can manipulate the second equation, making it x=y+14 by adding y to both sides. Then, now that we have an equivalent to x, we can plug it into the first equation to solve for y.
(y+14)+y=50
2y+14=50
2y=36
y=18
x+18=50
x=50-18
x=32
x=32, y=18
 
        
                    
             
        
        
        
Answer: k=225/2 
Decimal form: k= 112.5
Mixed number form: k=112 1/2
        
             
        
        
        
Greetings from Brasil...
First, let's make the mixed fraction improper:
- (3 3/8)
- { [(8 · 3) + 3]/8}
- { [24 + 3]/8}
- {27/8}
- (3 3/8) - (7/8)
- (27/8) - (7/8)
as the denominators are equal, we operate only with the numerators
- 34/8      <em>simplifying</em>
<h2>- 17/4</h2>
