Answer:
A function is a relation in which each input has only one output. In the relation, y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y.
Step-by-step explanation:
For every x there is exactly one y value. We can forgive a function if some values of x do not have a y, but if there is more than one y for even one value of x, then the relation is not a function.
Answer:
8/15
Step-by-step explanation:
Using Pythagorean Theorem the length of XZ is 15.
tan X = opposite / adjacent = YZ / XZ = 8 / 15.
Answer:
The missing value y=12.5 and we have (5,12.5)
Step-by-step explanation:
The formula used for direct variation is:

We need to find missing value (2,5)(5,y)
First we will find k, and then y
We have x=2, y=5
Find k:

Now, we cam find missing value in (5,y)
We have x=5, k=2.5 and y=?

So, the missing value y=12.5 and we have (5,12.5)
