As 27 will always be equal to 27, you can place whatever you want for x and y and the equation would still be satisfied, as it turns out that it doesn't depend on the x or y value.
Therefore, the system has infinite solutions.

Answer:
Lori will have 
cavity if she brushed for 
each night.
Step-by-step explanation:
As the question suggests cavities developed varies inversely with the number of seconds spent on brushing.
Lets take the terms as 
,where 
is the constant of proportionality.
And
c = Number of cavities developed each year
t = Number of minutes spent on brushing per night
Now we will plugging the values of the given terms and find the value of ,for this we can re-arrange it as...
and 
Now as Lori will increase her brushing time so as the cavity will decrease.
So for this we have been given,
and 
.
As 
So as per Paul's observation if Lori brushed for 
at night she will have cavity on that year.
Hi I would have to say 32,600 sorry if my answer sucks but I'm trying to help you the best I can :D
Explanation:
<u><em>* Demonstrate that the related angles are the same.</em></u>
<u><em>* Demonstrate that different interior angles are equivalent.</em></u>
<u><em>* Demonstrate the adjacent interior angles are supplementary.</em></u>
<u><em>* Demonstrate the adjacent external angles are not mutually exclusive.</em></u>
<u><em>* Show that the lines in a plane are perpendicular to the same axis.</em></u>
<u><em></em></u>
<1 and <8 are the same because they are alternate exterior angles that means that they are
Opposite sides of the transversal.
And that they are on the exterior side of the parallel lines.
Now because of that they have the same measures no matter what so would
<2 and <7
<3 and <6
<4 and <5
