Answer:

X= 4

Y= -2

Step-by-step explanation:

y - x = 6(1) \\ y + x =  - 10(2) \\  (1) + (2) \\ 2y + x - x =   - 10 + 6 \\ 2y =  - 4 \\ y =  - 2 \\ from(1) \\  - 2 - x = 6 \\  - 2 + 6 = x \\ x = 4

Answer:

  see attached

Step-by-step explanation:

Apparently, you're being asked to identify the sequence of steps you would use to compute the volume of the pyramid.

It seems to be a good idea to start with the formula for the volume.

Then, recognize that you need to compute B, so make that computation. The area of the base (B) is the product of the base dimensions (14)(12).

Once you have the value of B, then you can put that, along with the value of h, into the original volume formula.

Evaluating it gives the volume in cubic units.

_____

<em>Additional comment</em>

If you're familiar with the pyramid volume formula, you know that you must compute B before you can make use of the formula. That makes the sequence be B=14(12); B=168; V=1/3Bh; V=1/3(168)(7).

However, if you're starting from scratch, it is probably good to begin with the volume formula. That is what tells you that you need to find B in the first place. This is the sequence we show below.

ANSWER

The relation is not a function.

EXPLANATION

The relation is not a function because we have an x-coordinate mapping on to more than one y-coordinate.

This occurs at x=1.

The ordered pairs (1,1) and (1,3) disqualify the relation from being a function.

Hence the relation is not a function.

Which set of side lengths could be the sides of a triangle? A. 1 cm, 2 cm, 3 cm B. 5 cm, 9 cm, 18 cm C. 7 cm, 16 cm, 24 cm D. 10
antoniya [11.8K]
The answer is D because all the other go against the triangle inequality theorem. which states that the sum of the side lengths of any 2 sides of a triangle must exceed the length of the third side<span>
