The symbol to show that there are parallel lines is normally just a set
of vertical lines. Although if these are being drawn on a page and need
to be labelled as part of a shape or diagram, sometimes arrows will be
used to show they are parallel - either one arrow in the middle of the
line, or two arrows to show they are parallel but in different
directions.
Given:
The function is

To find:
The correct ordered pairs.
Solution:
We have,

For x=3,


So, the ordered pair is
.
For x=-2,

![[\because (\dfrac{a}{b})^{-n}=(\dfrac{b}{a})^n]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28%5Cdfrac%7Ba%7D%7Bb%7D%29%5E%7B-n%7D%3D%28%5Cdfrac%7Bb%7D%7Ba%7D%29%5En%5D)

So, the ordered pair is
.
For x=1,


So, the ordered pair is
.
For x=-1,

![[\because (\dfrac{a}{b})^{-n}=(\dfrac{b}{a})^n]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28%5Cdfrac%7Ba%7D%7Bb%7D%29%5E%7B-n%7D%3D%28%5Cdfrac%7Bb%7D%7Ba%7D%29%5En%5D)

So, the ordered pair is (-1,5). This is the correct answer.
Therefore, the correct option is D.
Let p = number of pennies.
Let n = number of nickels.
We are given that n= 2p and the total value is $8.80.
We know that a penny = $0.01 and that a nickel = $0.05.
So $0.01p + $0.05n = $8.80.
Substitute 2p for n:
$0.01p + $0.05*2p = $8.80
$0.01p + $0.10p = $8.80
$0.11p = $8.80
p = 80
So n = 2p = 2*80 = 160
Thus there are 80 pennies ($0.8) and 160 nickels ($8.00). The value of all the coins is $8.80.
