Answer:
whats the question
Step-by-step explanation:
Consider the given parallelogram KLMN.
Prove: 
Statement Reason
1.
Definition of parallelogram
2.
Same Side interior angle theorem


3.
Substitution property

4.
Subtraction property of equality

Subtraction property of equality tells us that if we subtract some number from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.
5.
Angle Congruence Postulate

When two angles are equal, then they are said to be congruent by Angle congruence postulate.
Answer: Choice B 
========================================================
Explanation:
They want to know what are all the possible y values here. The range is the set of all possible outputs of a function.
The largest y value is y = 0 which occurs at the vertex, in this case the highest point. There is no smallest y value as those arrows point downward forever.
So y is between negative infinity and 0, which means we write 
Converting that to interval notation leads to
. Note the square bracket to include the endpoint.
The compound inequality
simplifies to 
One way to describe this particular relation's range is to say "The set of negative real numbers with 0 included".
Side note: The domain is the set of all possible x inputs. In this case, the domain is the set of all real numbers.
