Answer:
No The reactions are not inverses to each other
Step-by-step explanation:
f(x) = 3x + 27
Let f(x) be y
y= 3x+27
subtracting 27 on both sides
3x = y - 27
x= (y-27)/3 
 = y/3 - 9
inverse function is x/3 -9 not x/3 + 9
Therefore, not an inverse

Let 

 be the length of the rectangle and 

 be the width. In the problem it is given that 

. It is also given that the area 

. Substituting in the length in terms of width, we have 

. Using the zero product property, 

. Solving these we get the width 

. However, it doesn't make sense for the width to be negative, so the width must be 

. From that we can tell the length 

. 
 
        
        
        
Answer:
it is D. the murmurs of a group
Step-by-step explanation:
 
        
                    
             
        
        
        
Area of a triangle = base x height / 2
64 = base x height / 2 
(multiply 2 on both sides) 
128 = base x height 
then if base= 16 and height = 8 then 16 x 8 = 128
thus the base is 16 which is twice the height:8
