I used a calculator to get the answer and it is correct.
Definition 1: A relation is any subset of a Cartesian product. For instance, a subset of 
, called a "binary relation from A to B," is a collection of ordered pairs (a,b) with first components from A and second components from B, and, in particular, a subset of 
is called a "relation on A."
Definition 2: A function is a relation that associates each element x of a set X to a single element y of another set Y (possibly the same set). A function is uniquely represented by its graph which is the set of all ordered pairs (x, f (x)).
From these definitions you can see that every function is a relation from X to Y, but not via versa (because you can consider relation 
- here for one x exist two y).
Answer: Correct choice is B.
Answer:
7
Step-by-step explanation:
20 • 35% = 13 20-13=7
Answer:
13
Step-by-step explanation:
ABC ~ DEF means that ABC and DEF are the same triangle either expanded or contracted.
In this case the scale factor is 1/2. That means DEF is half ABC.
Since AB = 26 then DE must be 26/2 = 13
