The table shows sets of ordered pairs that form a relation.
s2008m [1.1K]

Answer:

First 3 are functions . Last one is not a function

Step-by-step explanation:

They are all functions except the last one.

The last one is not a function because  it has duplicate  x- values  in the ordered pairs (1, -1) and (1, -6). There are 2 outputs for one input so its a relation but not a function

<h3>Answer:  Choice C.   (1,0)</h3>

============================================================

Explanation:

Point H is at (-2,2) and J is at (4,-2)

Focusing on the x coordinates, the midpoint is (x1+x2)/2 = (-2+4)/2 = 1.

The y coordinates have a midpoint of (y1+y2)/2 = (2+(-2))/2 = 0.

The midpoint is at (1,0). That's why the answer is choice C.

--------------------------

This next section is optional.

Points I and K are located at (4,3) and (-2,-3) respectively

Averaging the x coordinates gets us (x1+x2)/2 = (4+(-2))/2 = 1

Doing the same for the y coordinates gets us (y1+y2)/2 = (3+(-3))/2 = 0

We end up with the same midpoint (1,0)

The midpoint being the same for both diagonals proves that each diagonal is bisected, ie cut in half.

How do I get to the answer?<br><br> (3 x n) + 4 = 32/2<br><br> What is the value of n?
charle [14.2K]
If you simplify what's in the bracket, you get 3n

=(3n)+4=32/2
=3n+4= 32/2(here we can either crossmultiply or equate)
3n+4-4=32/2-4(subtract 4 from both sides)
3n=32/2-4
3n=24/2
3n=12
3n=12(divide both sides by the coefficient of the unknown)
3n/3=12/3
n=4
