Step-by-step explanation:
I believe it would just be y-15 because if there aren't anymore numbers then that is all you can do
The train will take 16 seconds to pass <em>completely</em> through a 300 meter tunnel.
Let suppose that the train moves itself at <em>constant</em> velocity, the vehicles needs to cover the tunnel length (
) and its length (
), both in meters, to pass through the tunnel, the time taken by the train (
) is described by the following kinematic formula:
(1)
Where
is the train velocity, in meters per second.
If we know that
,
and
, then the time taken by the train is:
![t = \frac{300\,m + 100\,m}{25\,\frac{m}{s} }](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B300%5C%2Cm%20%2B%20100%5C%2Cm%7D%7B25%5C%2C%5Cfrac%7Bm%7D%7Bs%7D%20%7D)
![t = 16\,s](https://tex.z-dn.net/?f=t%20%3D%2016%5C%2Cs)
The train will take 16 seconds to pass <em>completely</em> through a 300 meter tunnel.

Use n = 52 in the formula.
F = n/4 + 37
Replace n with 52:
F = 52/4 + 37
F = 13 + 37
F = 50
Answer: The estimated temperature is 50 deg F.
Y=-1x+5
First find the slope with the points. (b2-b1)/(a2-a1) (-2-6)/(7-(-1)) which equals -8/8
Then find the solve for b
-2=-1(7)+b
-2=-7+b
5=b
