x + 2y = 10

x + y = 6

Both x's in the equation are equal. We want the x of the last equation to be negative so we can eliminate.

x + 2y = 10

-x - y = -6

Subtract.

y = 4

Now that we figured out y, we have to figure out x. Substitute y into one on the equations.

x + 4 = 6

x = 2

Now we figured out x. The answer is (2,4). I hope this helps! Let me know if I got anything wrong or if you need any more help with this problem.

How do i do this? I dont really know where to start
Alex787 [66]
Well, I don’t necessarily remember how to sketch a plane. However, I can help get you started by defining some words they use and hopefully you will be able to do this on your own!

So this plane is made up of three points, names E, D and B. (Edit: This plane may be made up of four points, because of point A.)

E and B are collinear with A. This basically means that they all are on the same line.

D is a vertex. This basically means that it is a dot that these two lines called rays will shoot out of it. I will attach a picture of a vertex.

CD and FD are called rays. See those little lines above them? I’ll be sure to attached another image so that you know what I’m taking about. Anyway, that means they are rays. Rays are like never ending lines; they start at a point and the line will go on for infinity.

(Edit: where did the point f come from? I really wish you would have attached the full picture...)

Whelp, that’s all I’ve got! Good luck!!

(Edit: looks like I can only attach one picture...I’ll comment the other.)

Oh my life found out I have more homework help
Triss [41]

1. 8(-18d-10) = -144d-80

2. -13+14(-18+10d) = -13-252+140d = -265+140d

3. 15(-7x-3) = -105x-45

The number are quite weird but we have to deal with them.

The first and forth terms of a proportion are called the means.<br> Always<br> Sometimes<br> Never
natima [27]

Answer:

Never

Step-by-step explanation:

  • The first term (1st) and the fourth term (4th) of a proportion are called extreme terms or extremes, and the second term (2nd) and the third term (3rd) are called middle terms or means.
  • Therefore, in a proportion, product of extremes = product of middle terms.
