Answer:
80% because
Step-by-step explanation:
Answer:
It would be 0
Step-by-step explanation:
as both points lie on x-axis
In order to solve this problem, we need common denominators. 1/4 multiplied by 3/3 is 3/12. 2/3 multiplied by 4/4 is 8/12. 8/12 + 3/12 = 11/12. We also must add 2 and 16. 2 + 16 is 18. The box weights 18 11/12 pounds.
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!
x = -1
y = 1
To find this, input the equation into a graphing calculator, whether online or an actual one, and you have two options:
1 - Search for the points in which the line crosses the x and or y axis.
2 - Hit 2nd Graph to access the table and find when x and y equal zero.
Hope this helps!
