Find the sum of -395,102, -27, -95

1 answer:

4 0

Answer:

-415

Step-by-step explanation:

first, add -395+-27+-95, which equals -517

then, add 102 to -517(all you do is subtract 102 from 517 and put a negative sign in front of that answer), in which you would get -415.

Answer: x=-10, y=13

Step-by-step explanation:

$-3x+2y=56\\-5x-2y=24$

+2y-2y = 0, eliminating y is much easier. So -3x-5x = -8x and 56+24 = 80

$-8x=80\\x=-10$

Substitute x in any equations but only 1 equation (Don't substitute in both equations.)

For me, I'd substitute x in -3x+2y=50

$-3(-10)+2y=56\\30+2y=56\\2y=56-30\\2y=26\\y=13$

So the answer is x = -10, y = 13

Slope = (y2 - y1)/(x2 - x1) = (10 - 70)/(5 - (-15)) = -60/(5 + 15) = -60/20 = -3
