It always varies because solving a quadratic equation requires you to take a square root.
I do not have an answer to the second part of the first question.
As for the second question, I already answered it when you posted it separately.
Good luck :)

Answer:
(C) no solutions
Step-by-step explanation:
If you multiply the first equation by 2, you get ...
2x +2y = 4
When you compare this to the second equation ...
2x +2y = 8
you realize there are <em>no values of x and y that can satisfy both equations</em>. There are no solutions.
Answer:
y = -6 + 1.2*x is the answer I would use, but see the note below.
Step-by-step explanation:
Let x = the number of minutes.
Let y = the temperature at any given time.
y = -6 + 1.2*x
This is the equation that you would use if you were calculating y with a calculator. If you are in a chemistry class it should be written as
y = - 6°C + 1.2°x/ min
1, 3/3, 420/420 why such a wierd qustion
The width is 16 so the length is 64 (TO clarify W=16)
Hope this helps :)
