How can you tell if a table graph or chart represents a function

A function is a function if each x only has one y.

In a graph you can see this by doing a vertical line test. This would just be taking a vertical line and sliding it across the graph: if there is more than 1 point at any of the sections of the graph, then it's not a function.

In a table and chart: looking at the x's and if the same x value appears twice it's not a function.

The expression 14s(s - 1) can be used to find
Fantom [35]

Answer:

B. The variable s represents the number of students in each class.

C. The coefficient 14 represents the number of classes in the 9th grade.

Step-by-step explanation:

The total number can be found by multiplying the number of the things with the number of people producing it. For example if 5 boys make 5  colored ropes the total number of ropes will be 5*5= 25.

In this question the combinations rule is used for variuos number of classes which are 14. Now we have to find the number of students which are s (s-1). Suppose s= 6 so the number of students would be 6(6-1) = 6(5) = 30

We will multiply the number of classes 14 with the number of students s(s-1) to get the total number of cards produced.

Sergeeva-Olga [200]
In order for two triangles to be similar, there must be 2 pairs of congruent angles. Since two angles of triangle PQR have different measures from two angles of triangle RST, it is impossible to have two pairs of congruent angles, so the triangles cannot be similar.

The answer is in bold type below.

<span>All interior angles must be given to determine similarity.
The triangles are not similar.
Similarity cannot be determined from the given information.
The triangles are similar. </span>
