Answer:

The problem:

What can x not be so that the following is a function:

(8,5), (6, 8), (X, 11), (0, 12)?

Step-by-step explanation:

A set of points is a function if every element,x, in the domain is paired with one y from the range.

So basically we don't want any repeated x. x would be a repeat if x is 8 since it has already been paired with 5.

Summary we are saying x can't be 8 because x=8 is already paired with y=5 so we can't pair it with another different y.

Ksivusya [100]

Answer:

x= 16 degrees

Step-by-step explanation:

the angles can be a little hard to remember but just know that the angles that are outside of the transversal are exterior angles and if they are on the opposite sides of the line that passes through the parallel lines then they're alternate exterior angles and those angles that are inside are interior angles and if they are on the opposite sides of the line passing through the parallel then they are alternate interior angles .
