Explanation:
In order to prove that f is one-to-one and surjective, we can prove directly that f is bijective by findng .
To calculate the inverse of f, first we swap the variables x and y. Then we write y in values of x.
On this step it is important to separate what terms contain y and what terms do not. After that we can separate y as a factor
Thus, . Note that is well defined en every element of B, because it can be defined on any element different from 1, where the divider is zero.
An element of the form , for some x, is an element of A because it is different from -2. Lets suppose that there exist an x such as , thus 2x-1 = -2(1-x) = -2+2x, from where we conclude that 0 = -1, that is a contradiction. As a result, cant be equal to -2.
I hope this works for you!
The relationship between them is that one of them is 600 and the other 60. 60 times 10 is 600 so it is the next multiple of 10 of 60 is 600.
That is the most important relationship. Everything divisible by 60 is divisible by 600 and anything multiple of 600 is a multiple of 60.

Answer:
The answer is 16%
Step-by-step explanation:
use the percent error formula.
in this problem,
e= 75
t=90
substitute and solve.
16%
we are dealing with percents so rounding to nearest whole number will suffice.
hope this helps!
