For ever input, there is one ouput
it means we can't repeat the same x with a different y
but repeats of y's are allowed
pick any numbers that haven't been used as an input
-5 isn't taken
0 is taken
11 is taken
-1 is taken
2 is not taken
17 is taken
so -5 and -1 or A and D are the answers
Answer:

Step-by-step explanation:
we know that
The measure of the interior angle in an equilateral triangle is equal to 60 degrees
The measure of the interior angle in a regular octagon is equal to

where
n is the number of sides
In this problem we have

substitute


we have that, based in the diagram
The sum of the interior angle of the equilateral triangle plus the interior angle of a regular octagon plus the value of x must be equal to 360 degrees (complete circle)
so

solve for x



Answer:
goooooooooooooooooood
Step-by-step explanation:and you?
Step-by-step explanation:
Mean = Average : Sum of the data ÷ Number of data
So find the average number of lates per student
4 = Lates
30 (sum of frequencies) = Frequencies
So 4 ÷ 30 = 7.5
Therefore the answer is 7.5..
<h3>Explain why it is helpful to know the basic function shapes and discuss some ways to remember them. </h3>
- Knowing the basic function shapes and discuss some ways to remember them is helpful because this is useful tools in the creation of mathematical models because we constantly make theories about the relationships between variables in nature and society. Functions in school mathematics are typically defined by an algebraic expression and have numerical inputs and outputs.
