Hey guys! I need help solving this equation! The equation is:

Mathematics

Ok so you have your two equations:
(1) 2x + 3y = -11 (I am assuming you meant 2x + 3y instead of 2x + 3x at least?)
(2) x - y = 12
x = y + 12

If we substitute equation (2) into equation (1) we get:
2(y + 12) + 3y = -11
2y + 24 + 3y = -11
5y = -35, therefor y = -7

If y = -7, from equation (2) we get:
x = -7 + 12 = 5

SECTION OFFor the following figure, complete the statement for the specified points.Points Q, B, and C arecollinearcoplanarboth
olasank [31]

from given figure, we obtain that the points R, T and B are on the same line, that is, on the edge of the rectangular pyramid.

So these points are collinear.

Also all these points on the same plane. Therefore, the points R, T and B are collinear and coplanar.

The third option is the correct answer

Why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational numb
prisoha [69]

Part B seems to be missing, but I think I have enough information to be able to answer.

Let's say we had two numbers x and y. Let x be rational and y be irrational.

If x is some nonzero number, then x*y is irrational. The proof for this is a bit lengthy so I'll leave it out.

For instance,

x = 2 is rational, y = sqrt(3) is irrational, x*y = 2*sqrt(3) is irrational.

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

If we made x = 0, then

x*y = 0*y = 0

This is true for any value of y that we want. The y value doesnt even have to be irrational. It can be any real number.

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

So the distinction is that if x = 0, then x*y = 0 is rational since 0 is rational. Otherwise, x*y is irrational.
