Yis between x and z xy= 13.8 and xz= 21.4 find yz

yz = 7.6

Step-by-step explanation:

Since, y lies in between x and z.

Thus, xy + yz = xz

⇒ yz = xz - xy

Also, we have, xy = 13.8

xz = 21.4

Hence, yz = 21.4 - 13.8

⇒ yz = 7.6

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
