Answer:
-7/2 or -3.5
Step-by-step explanation:
Make the equation first
7x-1 = 5x-8
7 = -2x
-7/2 = x
 
        
                    
             
        
        
        
Answer:
(gof) (4) = 9
Hence, option A is true.
Step-by-step explanation:
f(x)=-x³
g(x)=|1/8x -1|
(gof) (4) = g{f(4)}
First wee need to determine f(4)
f(4)=-(4)³ 
     = -64
so
   (gof) (4) = g{f(4)} = g(-64)
                              =  
                              
                              
                              

                               
         
Thus, 
(gof) (4) = 9
Hence, option A is true.

Answer:
(30, ∞)
Step-by-step explanation:
b – 27 > 3 
Add 27 to both sides
b > 30
In interval notation
(30, ∞)
