The answer is: 3.
_________________
In the table, the relation (x, y) is not a function is the "missing value" of "x" is: 3.
_______________________________________
Explanation: We are given that the ordered pair: "(3,10)" exists.  In other words, when x = 3, y =10. 
______________________________________
The "missing value" refers to the "empty box" in the table shown (in the attached screenshot).  The "empty box" shows a "y-coordinate" of "20"; but a "missing" corresponding "x-coordinate".
____________________________________
The problem asks: 
_________________
In the table, the relation (x, y) is not a function is the "missing value" of "x" is: ____?
___________________
The answer is: 3.
_______________________
We know the answer is "3"; because we know that "3" already has 1 (one) corresponding y-coordinate.

By definition, a "function" cannot have ANY "x-coordinates" that have more than one "corresponding y-coordinate".   As such:
_______________________________________
In the table, the relation (x, y) is not a function is the "missing value" of "x" is:
____________
3.
____________
Additional information:
____________
When examining an equation on an actual graph, we can use what is called the "vertical line test".  That is, one can take a pencil and vertically go through the "y-axis", or even examine it visually, to see if there are any "x-values" that have more than one corresponding "y-coordinate".
   If no, then it "passes" the "vertical line test" and is a "function".  
If not, then it does NOT pass the "vertical line test" and is NOT a function.

Which statement best describes the relation (3, 4), (4, 3), (6, 3), (7, 8), (5, 4)?
snow_lady [41]

Answer:

This relation represent y as a function of x, because each value of x is associated with a single value of y

Step-by-step explanation:

we know that

A function is a relation from a set of inputs (x values) to a set of possible outputs (y values) where each input is related to exactly one output

we have the relation

(3, 4), (4, 3), (6, 3), (7, 8), (5, 4)

This relation represent y as a function of x, because each value of x is associated with a single value of y

what is the value of y in the solution to the following system of equations? (5 points) 2x y = −4 5x 3y = −6
TiliK225 [7]
2x+y=-4
5x+3y=-6

multiply first equaton by -5 and second by 2 then add them

-10x-5y=20
<u>10x+6y=-12 +</u>
0x+1y=8

y=8

the y value is 8
