B. The diagonals bisect each other.
The correct answer is A. Think of this as a graph in the y=Mx+b form. When graphing these equations, you should be able to see that the lines for A and B match up with the picture. However, since everything below the line is shaded, this must mean that the graph includes everything under the line. Y must be less than everything that is input. The correct answer is A.
-R
The domain of a relation is the set of all the x-terms of the relation.
Let's look at an example.
In the image provided I have attached a relation and we want to list the domain.
So, I will list all the x-terms. Notice however that I listed 7 once even though it appears twice in the relation. When listing the domain, you don't repeat the x-terms.
To solve this question we must first find out what is x.
X + x - 4 = 82 degrees
2x - 4 = 82
2x = 86
X = 86/2 = 43.
Here x would be 43 degrees.
We can add up the angles because we know the angle of DAC and the CAB angle add up to give 82 degrees.
