Evaluate the triple integral.

Irina-Kira [14]

The definition of the set E gives you a natural choice for the limits in the integral:

$\displaystyle \iiint_E y \, dV = \int_0^6 \int_0^x \int_{x-y}^{x+y} y \, dz \, dy \, dx$

Computing the integral, we get

$\displaystyle \iiint_E y \, dV = \int_0^6 \int_0^x y ((x+y)-(x-y)) \, dy \, dx = 2 \int_0^6 \int_0^x y^2 \, dy \, dx$

$\displaystyle \iiint_E y \, dV = 2 \int_0^6 \frac13 (x^3 - 0^3) \, dx = \frac23 \int_0^6 x^3 \, dx$

$\displaystyle \iiint_E y \, dV = \frac23 \cdot \frac14 (6^4 - 0^4) = \boxed{216}$

What does it mean when two such lines intersect? What can you say about the solution of the two equations?

Illusion [34]

If two lines intersect, and intersect only at one point, then the coordinates of that point satisfy the equations of the lines.

If, on the other hand, one line coincides with the other, then there are an infinite number of solutions.
