Because you have to flip ur fraction to make a reciprical
Answer:
Below
Step-by-step explanation:
Well I can't really see the equation but I can tell you how to do it.
Parallel slopes are the same slope as the equation.
For example, y = mx + b
The slope of a line parallel to it is m
Perpendicular slopes are the opposite reciprocal as the equation.
For example, y = mx + b
The slope of a line perpendicular to it is![-\frac{1}{m}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7Bm%7D)

Answer:
A. (f-g)(x) = -5^x +3x -2
Step-by-step explanation:
The only terms that can be combined are the constants.
(f -g)(x) = f(x) -g(x)
(f -g)(x) = (-5^x -4) -(-3x -2) = -5^x -4 +3x +2
(f -g)(x) = -5x^4 +3x -2 . . . . . matches A
