3 equivalent fractions are 4/10 , 10/25 and , 6/15
        
             
        
        
        
The correct answer is:  " √x  −  <span>2√b " .
</span>_________________________________________________________
       The "conjugate" of  " √x  + 2√b "  is:  " √x  −  2√b " .
_________________________________________________________
Explanation:
_________________________________________________________
      In an expression with 2 (TWO) terms;  that is, in a "binomial expression", 
the "conjugate" of that expression refers to that very expression — with the "sign" in between those two terms—"reverse" (e.g. "minus" becomes "plus" ; or, "plus" becomes "minus" .) .
_________________________________________________________ 
      →  So:  We are given:  " <span>√x + 2√b " .
</span>
      →  Note that this is a "binomial expression" ;
      →  that is, there are 2 (TWO) terms:  " <span>√x " ; and:  " 2√b " .
_________________________________________________________
To find the "conjugate" of the given binomial expression:
     </span>→  " <span>√x + 2√b "  ; 
     </span>→  We simply change the "+" {plus sign} to a "<span>−"  {minus sign} ;  and rewrite:
___________________________________________________________
     </span>→  " √x − 2√b "  ; 
     →  which is the "conjugate" ; and is the correct answer:
___________________________________________________________
→  " √x − 2√b " ;   is the "conjugate" of the expression:  " <span>√x + 2√b " . 
___________________________________________________________
     </span>→  {that is:  " √x − 2√b " ;  is the conjugate.}.

Answer:
   (f×g)(2) = 3/4
Step-by-step explanation:
For each of the functions, put 2 where x is and evaluate the expression.
   f(2) = (3 -2)/(2² +4) = 1/8
   g(2) = 3×2 = 6
Then the product is ...
   (f×g)(2) = f(2)×g(2) = (1/8)×6 = 6/8
   (f×g)(2) = 3/4
 
        
             
        
        
        
Answer:
f=110132.328974hti
Step-by-step explanation:
 
        
             
        
        
        
f(x) = (3x+5)/7
Step 1:
we write f(x) as y
y=(3x+5)/7
Step 2:
switch y by x and x by y
x=(3y+5)/7
Step 3:
solve for y,
x=(3y+5)/7
multiply both sides by 7
7x=3y+5
subtract 5 from left side
3y=7x-5
divide both sides by 3
y= (7x-5)/3
f⁻¹ (x) =(7x-5)/3
