Answer:

Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(8x - 13)
= 
= 
 
        
             
        
        
        
The answer is B, the green is f(x)=x^2 and the red one is g(x)=f(2x).
 
        
        
        
1/2 a bunch because 8 divided by 4 = 1/2 :)
        
             
        
        
        
Answer:
x² - 5x = 14
x = -2   or   x = 7
Step-by-step explanation:
x² - 5x = 14
x² - 5x - 14 = 0
(x+2)(x-7) = 0
x = -2   or   x = 7
 
        
             
        
        
        
Answer:
1
Step-by-step explanation:
x-7=-5x-1
x-(-5x)-7=-1
x+5x-7=-1
6x-7=-1
6x=-1+7
6x=6
x=6/6
x=1
