128.04 - 8.287
= 119.753
Answer:
(-4,-1)
Step-by-step explanation:
-3x+10y=2
-3x+3y=9
-3x=2-10y
-3x=9-3y
2-10y=9-3y
2-9=10y-3y
7y=-7
y=-1
-3x+3(-1)=9
-3x-3=9
-3x=12
x=-4
In order for <em>F</em> to be conservative, there must be a scalar function <em>f</em> such that the gradient of <em>f</em> is equal to <em>F</em>. This means


Integrate both sides of the first equation with respect to <em>x</em> :

Differentiate both sides with respect to <em>y</em> :

But we assume <em>g</em> is a function of <em>y</em>, which means its derivative can't possibly contain <em>x</em>, so there is no scalar function <em>f</em> whose gradient is <em>F</em>. Therefore <em>F</em> is not conservative.
Start by laying out the 12.
The neighbors of 12 must be 11 and 10.
The neighbor of 11 must be 9, and the neighbor of 10 must be 8, and so on and so forth, until you get a unique arrangement.
