Answer:
solution is (- 3, 5 )
Step-by-step explanation:
given the 2 equations
6x - y = - 23 → (1)
8x + 3y = - 9 → (2)
rearrange (1) expressing y in terms of x
y = 6x + 23 → (3)
Substitute y = 6x + 23 into (2)
8x + 3(6x + 23 ) = - 9
8x + 18x + 69 = - 9
26x + 69 = - 9 ( subtract 69 from both sides )
26x = - 78 ( divide both sides by 26 )
x = - 3
substitute x = - 3 into (3)
y = (6 × - 3 ) + 23 = - 18 + 23 = 5
solution is (- 3, 5 )
<span>Interest=principle x rate x time (in years)
so putting values so
Interest=7500 (.042)(2)
so
Interest=630
7500+630=8130
Interest=500 (.071)(4)
Interest=142
500+142=64

For 
to be conservative, we need to have
Integrate the first PDE with respect to 
:
Differentiate with respect to 
:
Now differentiate 
with respect to 
:
So we have
so is indeed conservative.
I think its ummm uhhh mmmm uhhhh
