48/31 is already at its simplest form, however you can change it to a mixed fraction which would become 1 17/31
 
        
                    
             
        
        
        
That’s how you plug it in and get the answer because when you plug in z and y value correctly you just have to follow the rule and simplify 
So final answer would be +2
 
        
        
        
False, it is not a repeating decimal
9/4 = 2.25
        
             
        
        
        
Answer:
Answer of 17 is  ㏒( +15x), Answer of 33 is x = 8 , Answer of 35 is x = ㏒10/㏒2 , Answer of 37 is  x = -㏒12/㏒8 and Answer of 39 is x = 5
+15x), Answer of 33 is x = 8 , Answer of 35 is x = ㏒10/㏒2 , Answer of 37 is  x = -㏒12/㏒8 and Answer of 39 is x = 5
Step-by-step explanation:
 17. ㏒x + ㏒(x+15)
      Using property ㏒a + ㏒b = ㏒a×b
      ∴ ㏒x + ㏒(x+15)
         ㏒x×(x+15)
         ㏒( +15x)
+15x)
         The answer is ㏒( +15x)
+15x)
33. 2^(x-5) = 8 
      2^(x-5) = 2^3 
       Using property 2^a = 2^b
       Then a = b
      ∴x-5 = 3
        x = 8 
       The answer is x = 8
35. 2^x = 10
     Taking log on both sides gives
      ㏒2^x = ㏒10
      x×㏒2 = ㏒10
      x = ㏒10/㏒2
      The answer is x = ㏒10/㏒2
 37. 8^-x = 12
     Taking log on both sides gives
      ㏒8^-x = ㏒12
      -x×㏒8 = ㏒12
       x = -㏒12/㏒8
      The answer is  x = -㏒12/㏒8
 39. 5(2^3 × x) = 8
       5(8×x) = 8
       x = 5
      The answer is x=5
   
 
        
             
        
        
        
Answer:
$12,000,000
Step-by-step explanation:
The maximum will be the vertex and because this is written in vertex form the vertex will be (5, 12) so the maximum income will be 12 million dollars.
