Answer:
36 = 2x + y
x = y
x = 12
y = 12
Step-by-step explanation:

Divide both sides by
:
![x\dfrac{\mathrm dy}{\mathrm dx}+y=\dfrac{\mathrm d}{\mathrm dx}[xy]=-\dfrac{\sec(xy)}{x^3}](https://tex.z-dn.net/?f=x%5Cdfrac%7B%5Cmathrm%20dy%7D%7B%5Cmathrm%20dx%7D%2By%3D%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Bxy%5D%3D-%5Cdfrac%7B%5Csec%28xy%29%7D%7Bx%5E3%7D)
Integrate both sides to get

where
and
are constants, and divide by
to solve for
:

An exact solution (not in terms of a definite integral, anyway) doesn't seem likely...
Answer:
3x-7+7
Step-by-step explanation:
Answer:
Your answer is right. The sequence has a pattern of -4 every time, so it's A
Graph B would be the best fit for the model.
