Answer:
364.5
Step-by-step explanation:
you would need a calculator for it, unless you can do exponential math at such a degree... if you're using a PC there's a good graphing calculator at Desmos.com, it can show you how a graph looks, which shows that when n is 7, the answer is 364.5. also it wouldn't be 1093.5 because the exponent is n-1 which means that while n could be 7, you need to take away 1 before using it as an exponent.
 
        
                    
             
        
        
        
Answer:
(f+g)(x) = 13x + 3
Step-by-step explanation:
Rewrite  f(x)=2x+7 and g(x)=11x-4 in columns, as follows:
 f(x)=2x+7
+g(x)=11x-4
----------------
Now add each column separately.
f(x)+g(x) = (f+g)(x) ("the sum of functions f and g")
2x + 11x = 13x, and, finally, 7-4 = 3.
Therefore, 
  f(x)=2x+7
+g(x)=11x-4
----------------
(f+g)(x) = 13x + 3
