The domain of (f/g)(x) considers the domains of g(x) and f(x) and makes sure that g(x)≠0
because (f/g)(x)=f(x)/g(x)
and division by 0 is not allowed
the domains of f(x) and g(x) are all real numbers
now find what make g(x)=0
0=x-9
9=x
9 is restricted from the domain
domain is all real numbers except 9
so


the domain is all real numbers except for 9
 
        
        
        
Answer:
x=-5
Step-by-step explanation:
25 - 3x = 40
-3x + 25 =40
-3x +25--25=40-25
-3x=15
-3x÷-3=25÷-3
x=-5
 
        
                    
             
        
        
        
Answer:
1, -6
Step-by-step explanation:
Since there are alike numbers, add them together.
4x+x= 5x
Now the function is: f(x)=  +5x-6
+5x-6
The function is in   +bx+c form.
+bx+c form.
So find the factors of a x c = b.
Factors of -6(a) that fits (b)5 is (-1,6).
Then you just factor it:
f(x)=  +5x-6
+5x-6
(x-1)(x+6)
x-1= 0  x+6=0
  +1 +1     -6  -6
x=1      x=-6
Those are the real zeroes: 1, -6
 
        
             
        
        
        
7/8 is written as a decimal is 0.875
        
             
        
        
        
Answer: not a function 
It’s not a function because 9 repeats
