Answer:
a). 0 
Step-by-step explanation:
f(1) = 1 - 1
= 0 
 
        
                    
             
        
        
        
Answer:
therefore angle Y will be equal to angle X by vertically opposite angle as by taking all the angles inside the traingle will be equal to Y so Y = X = 60°

 and  values from the coordinate pair (5, 2) into the given equation,
 values from the coordinate pair (5, 2) into the given equation,  . if both sides of the equation end up equal, the coordinate pair is a solution to the equation. if not, the coordinate pair is not a solution to that equation.
. if both sides of the equation end up equal, the coordinate pair is a solution to the equation. if not, the coordinate pair is not a solution to that equation.
<em>(i hope i explained that well enough, i'm better at explaining it algebraically as opposed to putting it into words lol)</em>
<u>answer (algebraic/steps for solving)</u>
first, plug in 5 for  in the equation
 in the equation  .
.
 ⇒ ⇒ 
then plug in 2 for  .
.
 ⇒ ⇒ 
now your equation is  . all that's left to do is to simplify. you can do this in whatever order you'd like, but i'll start with multiplying 2 · 5.
. all that's left to do is to simplify. you can do this in whatever order you'd like, but i'll start with multiplying 2 · 5.
 ⇒ ⇒ 
multiply 3 · 2.
 ⇒ ⇒ 
add 10 + 6.
 ⇒ ⇒ 
16 and 10 are <em>not</em> equal, therefore (5, 2) is not a solution to the equation  . in order for a coordinate pair to be the solution to an equation, both sides of the equation need to end up equal after solving and simplifying.

i hope this helps! have a great rest of your day <3
