Answer:
 <em>Yes</em> 
Step-by-step explanation:
g(x) = - 
 x + 
 
y = - 
 x + 
 ....... <em>(1)</em> 
<em>(1)</em> × 4 
4y = - x + 1 
x = - 4y + 1 
y = - 4x + 1 
f(x) = - 4x + 1 
∴ f(x) and g(x) <em>are inverses</em>

Answer:
2x + 12
Step-by-step explanation:
Example of Associative Property Addition:
a + (b+c) = b + (a+c)
Now, implement it to the given expression:
(2x+8) + 4 = 2x + (8+4)
That simplifies to:
2x + 12
 
        
                    
             
        
        
        
Answer:
8 hours
Step-by-step explanation:
6x+20=68 
subtract 20 from both sides
6x=48
divide 6 both sides
x=8
