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=-24 is the correct answer
Hey there! :D
If 20 is 25% of a number,
we know that it is a quarter of a number.
20*4= 80
20 is 25% of 80.
I hope this helps!

Answer:
2156/9
Explanation:
The question states all the necessary values that we need for the ratio. The company created 2156 board games and 9 card games.
However, what we need to pay attention to here is the order of the ratio.
Because the question is “What is the ratio of the number of board games to the number of card games”, we know that we need to write the ratio so the number of board games is first.
Additionally, ratios can also be written like fractions. The first number of the ratio would be the top number/numerator in fraction form.
Therefore, the ratio of the number of board games to the number of card games is 2156:9
