Answer:
B 0
Step-by-step explanation:
r is a horizontal line
horizontal lines are of the form y= constant
The slope for horizontal lines are 0
Parallel lines have the same slope.
I do believe it is answer c, but not 100% on that due to the fact that when i worked it i got c, but when i googled alot got other answers. sorry i know thats not much help
Answer:
+1 and -1
Step-by-step explanation:
The function in this problem is:

First of all, we have to define the domain of the function, which is the set of values of x for which the function is defined.
In order to find the domain, we have to require that the denominator is different from zero, so

which means:

So the domain is all values of x, except from 4 and -7.
Now we can solve the problem and find the zeros of the function. The zeros can be found by requiring that the numerator is equal to zero, so:

This is verified if either one of the two factors is equal to zero, therefore:

and

We see that both values are part of the domain, so they are acceptable values: so the zeros of the function are +1 and -1.
Divide by 10000 to go to kilometer from centimeter
and km is not a weight unit
Answer:
These are the steps to do it since there is no equations provided
Step-by-step explanation:
1.) First, replace f(x) with y . ...
2.) Replace every x with a y and replace every y with an x .
3.)Solve the equation from Step 2 for y . ...
4.) Replace y with f−1(x) f − 1 ( x ) .
