Answer:None</h2>
Step-by-step explanation:
For any function,any point in the domain has a unique image in the codomain.
For set 
:
from the point 
from the point 
For a same point 
,there are two images.
So, does not represent a function.

Answer:
length 11 width 4
Step-by-step explanation:
perimeter:
11+11=22
4+4=8
22+8=30
area:
11*4=44
Answer:
reactants
A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
Step-by-step explanation:
Answer: I think its combining like terms
I'm not 100% sure though sorry
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: Is the slope
b: Is the cut-off point with the y axis
According to the data of the statement we have to:
Then, the equation is of the form:
We substitute the point
and find "b":
Finally, the equation is:
To graph we place the points 
and
on the coordinate axis and join the points by a line.
