4-2y+3=-9<br><br> What is y?
Yanka [14]

Answer:

y=8

Step-by-step explanation:

4−2y+3=−9

Step 1: Simplify both sides of the equation.

4−2y+3=−9

4+−2y+3=−9

(−2y)+(4+3)=−9(Combine Like Terms)

−2y+7=−9

−2y+7=−9

Step 2: Subtract 7 from both sides.

−2y+7−7=−9−7

−2y=−16

Step 3: Divide both sides by -2.

−2y

−2

=

−16

−2

Use Green's Theorem to find the work done by the force F(x, y) = x(x + y) i + xy2 j in moving a particle from the origin along t
Murljashka [212]

x+y=6 is the equation of the line through the points (6, 0) and (0, 6).

By Green's theorem,

\displaystyle\int_C\vec F(x,y)\cdot\mathrm d\vec r=\iint_D\left(\frac{\partial(xy^2)}{\partial x}-\frac{\partial(x(x+y))}{\partial y}\right)\,\mathrm dA

where C is the given path and D is the triangular region with C as its boundary. We have

\displaystyle\iint_D(y^2-x)\,\mathrm dA=\int_0^6\int_0^{6-x}(y^2-x)\,\mathrm dy\,\mathrm dx=72
