Answer:
- f(x) = x
- g(x) = -2x+1
- f(x) -(-g(x)) = -x+1
- f(x) +g(x) = -x+1
- f(x)-(-g(x)) = (f+g)(x) is true for all functions f and g, linear or not
Step-by-step explanation:
We can define a couple of linear functions as ...
f(x) = x
g(x) = -2x+1
Then the reflected function -g(x) is ...
-g(x) = -(-2x +1) = 2x -1
And the difference from f(x) is ...
f(x) -(-g(x)) = x -(2x -1) = -x +1 . . . . f(x) -(-g(x))
We want to compare that to the sum of the functions:
f(x) +g(x) = x +(-2x +1) = -x +1 . . . . f(x) +g(x)
The two versions of the function expression have the same value.
These results are <em>a property of addition</em>, so do not depend on the nature of f(x) or g(x). They will hold for every function.

Answer:</h3>
4) ÷10
5) Yes
<h3>
Step-by-step explanation:</h3>
<em>Question 4</em><em>:</em>
Just take the first number 322 and plug in the choices.
At the end the only one that will finish with all exactly like the pattern is ÷10.
<em>Question</em><em> </em><em>5</em><em>:</em>
We know Logan's watch is still under warranty because,
1 week = 7 days.
6 weeks × 7 days = 42 days
But he has 90 days, so there is still more than 50 days that he can go return it and will get his money back.
<h3>Hope this Helps!!</h3>

<h3>No it does not form a triangle!~</h3>
Let's prove it by pythogoras theorem,
- Hypotenuse = 23
- Base = 7
- Perpendicular = 16
<h3>Hence (Proved) </h3>
Answer:
Subtract 14 from both sides of the equation.
Step-by-step explanation:
The subtraction property of equality tells you the equal sign only remains valid if you subtract the same value from both sides of the equation.
Here, we want the 14 on the left side to be replaced by 0. Thus we must add its opposite. Since we must do the same thing to both sides of the equation, we must <em>subtract 14 from both sides of the equation</em>.
