\dfrac\partial{\partial y}\left[e^{2y}-y\cos xy\right]=2e^{2y}-\cos xy+xy\sin xy

\dfrac\partial{\partial x}\left[2xe^{2y}-y\cos xy+2y\right]=2e^{2y}+y\sin xy

The partial derivatives are not equal, so the equation is not exact.

G(n) = 4n+1<br> h(n)= -2n+3<br> Find (g+h)(n)
Mice21 [21]

Answer:

14 - 4n

Step-by-step explanation:

g = 4n+1/n

n = 1/g−4

---------------------------------------

h = −2n+3/n

n = 3/h+2

---------------------------------------

g(- n + 3) = 4(- n + 3) + 2 = - 4n + 12 + 2 = 14 - 4n

The question that you have input is clearly wrong. It's not a quardratic equation. 10X2 doesn't make any sense for a quadratic equation. You should change it to 10x^2 which would make more sense

Use substitution when either and x or y is given, for instance: x = 2y + 3 or y = 8x - 9.

Use elimination when a number from both equations can cancel each other out, for example:
2x + 3y = 19
-2x + 7y = 12

Hope this helps!
