Answer:
C
Step-by-step explanation:
Answer with Step-by-step explanation:
We are given that

For each real number 
To prove that f is one -to-one.
Proof:Let
and
be any nonzero real numbers such that

By using the definition of f to rewrite the left hand side of this equation

Then, by using the definition of f to rewrite the right hand side of this equation of 

Equating the expression then we get




Therefore, f is one-to-one.

Step-by-step explanation:
Answer:
52.5
Step-by-step explanation:
=50+50×5%
=50+2.5
=52.5

1) As we can see this is a Linear Equation written in the Slope-intercept form:

Note that "m" stands for the slope of the line, i.e. the measure of how steep a line is.
In the given equation, we can state that the slope is always accompanying the "x" therefore, the slope is m= 7
2) In addition to this, the y-intercept also called the Linear Coefficient is given by the letter"b" and represents the y-coordinate that the graph intercepts. Thus the y-intercept is -6
So we can state the following as the answers:

And that is the answer
