Step-by-step explanation:
f'(x) is usually used in calculus to denote the first derivative of f(x) so f'(2) will simply be the first derivative of f(2).
f(x)=x+3
f'(x)=1
thus x does affect the first derivative and your answer for f'(x)=1
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Not in standard form. The coefficients should be integers and the coefficient of x should be positive. 
x+6y=30
Note that the choices given are not in standard form.

Answer:
m=148
Step-by-step explanation:
2=m/2 -72
2+72=m/2
74*2=m
m=148
