Solve 4x+y=8 x+y=5 Solving by elimination

Ulleksa [173]

Answer:

y=4,x=1

Step-by-step explanation:

4x+y=8

x+y=5

subtract equation 2 from equation 1

3x + 0=3

3x=3

divide both sides by 3

x=1

substitute for x=1 in equation 2

x+y=5

1+y=5

y=5-1(collecting like terms)

y=4

kipiarov [429]

Let $R$ be the ellipsoid with equation

$\left(\dfrac xa\right)^2+\left(\dfrac yb\right)^2+\left(\dfrac zc\right)^2=1$

so that the volume of $R$ is given by the triple integral

$\displaystyle\iiint_R\mathrm dV$

Consider the augmented spherical coordinates given by the identities

$\begin{cases}x=ar\cos u\sin v\\y=br\sin u\sin v\\z=cr\cos v\end{cases}$

Computing the Jacobian, we find that the volume element is given by

$\mathrm dV=\mathrm dx\,\mathrm dy\,\mathrm dz=abcr^2\sin v\,\mathrm dr\,\mathrm du\,\mathrm dv$

so that the volume integral can be written as

$\displaystyle\iiint_R\mathrm dV=abc\int_{v=0}^{v=\pi}\int_{u=0}^{u=2\pi}\int_{r=0}^{r=1}r^2\sin v\,\mathrm dr\,\mathrm du\,\mathrm dv=\frac{4abc\pi}3$

|-3 + 15| what is the sum (answer) ? I think it is 12 but my friend thinks it is 18. Who is right?

Aliun [14]

I do believe it is 12 as well considering the fact that it's negative three and not positive. If it was a positive three then maybe it would be 18.
