Answer: 
Step-by-step explanation:
Step 1:-
Given equations are y=-2 x+30........(1)
    another equation is y=4 x ..........(2)
Step 2:-
solving these two equations (1) and (2)
Equating both equations are  


Step 3:-
The final answer is 
                                                  
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Unclear.  Did you mean f(x) = 2^(x + 3)?  If so, the parentheses are mandatory.
Assuming that f(x) = 2^(x + 3) is correct, then:
a) f(2) = 2^(2 + 3) = 2^5 = 32
b) f'(x) = 2^(x + 3)*(x + 3)' = 2^(x + 3)(1) = 2^(x + 3)
c) f"(x) = 2^(x + 3) (same as in (b)), so that:
    f"(12) = 2^15
 
        
             
        
        
        
Answer:

Step-by-step explanation:
It would take me a million years to show you how to solve it but its long division
 
        
                    
             
        
        
        
X/10 = 10/4x
4x^2  = 100
  x^2 = 25
     x = 5
