Y'sinx=ylny, is equivalent to <span>dy / dx (sinx=ylny, and </span><span>dy sinx=ylny dx
it is similar to dy/</span>ylny = dx/sinx
so integral (dy/ylny = integral dx/sinx)
integral dx/sinx)= Ln{abs value ( tan(x /2 + pi /4)}
integral (dy/ylny= ln(lny)
final answer is lny = {abs value ( tan(x /2 + pi /4)}+C, you can find y, or x
52 i believe.
42 + 45 + 58 + 63 = 208
208 / 4 = 52
We are given a system of equations,

This will translate into a 2x2 matrix of coefficients (because 2 equations and 2 unknowns),

The matrix will then be applied to the vector (lower dimensions on top),

And the result vector will be whats on the other side of equals sign,

So to put everything together,

Hope this helps :)
Note that the slope-intercept form is: y = mx + b
First, set the equation as such
2x (-2x) + 3y = (- 2x) + 15
3y = -2x + 15
Isolate the y. Divide 3 from both sides
(3y)/3 = (-2x + 15)/3
y = (-2/3)x + 5
-2/3 is your slope
hope this helps
