Answer:
A) 
B) 
C) 
Step-by-step explanation:
So we have the equation:

Let's write this in function notation. Thus:

A)
To flip a function over the x-axis, multiply the function by -1. Thus:

Simplify:

B) To flip a function over the y-axis, change the variable x to -x. Thus:

Simplify:

C) A reflection over the line y=x is synonymous with finding the inverse of the function.
To find the inverse, switch x and f(x) and solve for f(x):

Switch:

Subtract 4 from both sides:

Divide both sides by 5:

And we're done :)
In order to check whether the length of the sides are applicable to form a triangle is that we have to make sure that the sum of the length of two side should be greater than the third side.
<span>18.5 m, 36.9 m, and 16.9 m
18.5 m < </span><span>36.9 m +16.9 m
</span>36.9 m < 18.5<span> m +16.9 m
</span>16.9 m < 18.5 m + <span>36.9 </span>m
So the dimensions are correct!
