The sum of 5+2 or 2+5 is 7. It's the same because it doesn't matter if the equation is flipped around in addition.
Since we are given x in terms of y, the most efficient way to solve it would be to substitute in the for x in the second equation. So, we then have:
So, now that we have our y, we can find x. We can actually use either equation, top or bottom, to find x, but to be efficient we should use the top one since we have x in terms of y, so:
So, our ordered pair is (2,-6).
Answer:
These are easy you should know

But it looks like you got the answers already God Bless
The population is all of the wild elephants. The sample is the 400 wild elephants selected.
Y=-1/2x-3
You can rewrite the equation “y=mx+b” and fill in what you know. So your equation would look like y=-1/2x+b when filling in what you know. Now you can take the (x,y) coordinates that you were given and plug them into the equation and solve for b. So now it would be -5=-1/2(4)+b
