Try y=-2x-3 (I think that should be it)
Hello! There are a few things that determine whether or not something is a function. In this case, to determine whether a relation is a function, we look at the domains, which are the x-coordinates, the first number of the pair. If the number occurs in the x-coordinate for more than one pair in a relation, then it's not a function. If a number only occurs as an x-coordinate once in the relation, then it's a function. In other words, they each have only one y-coordinate in the relation. For this question, the first, second, and third relations are functions. The fourth one is not a function, because the 3 has more than one y-coordinate, so it occurs as an x-coordinate more than once. Here are the answers easier to read.
1st : yes
2nd: yes
3rd: yes
4th: no

Answer:
x is 72 degrees
Step-by-step explanation:
To find the measure of x, you need to know the sum of the interior angles of the pentagon.
Sum = (n - 2) x 180
Sum = (5 - 2) x 180
Sum = 3 x 180
Sum = 540
Now divide this by 5, the number of sides
540/5 = 108 degrees for each angle of the pentagon.
To find the measure of x, look at the opposite angle, which is 108 degrees
180 - 108 = 72
The measure of angle x is 72 degrees.
