Mathematics
1 answer:
WARRIOR [948]3 years ago
4 0

Answer: (x,y) = (-10, -9)

Step-by-step explanation:

(By replacement method ...)

1-  x = -2-8 it's the same thing as x = -10.

2- Replace the given value of x in equation 3x - 4y = 6

Replacing ...

3 * (-10) -4y = 6

3- Then, Multiply 3 by -10;

4) Move -30 to the right side of the equal sign, getting: 6 + 30.

-4y = 36

5) Multiply by -1

-4y * (- 1) = 36 * (- 1) is equal to 4y = -36

6) The four is multiplying the y, so pass the four <u>dividing</u>, getting:

-36/4

The ratio of -36 by 4 equals <u>-9.</u>

Therefore...

x = -10

y = -9

PLEASE HELP! WILL MARK BRAINLIEST!
Kaylis [27]

Answer:

320 meters

Step-by-step explanation:

x² + 200x = 166400

It's a square, area should be side²

x² + 2(x)(100) = 166400

x² + 2(x)(100) + 100² = 166400 + 100²

(x + 100)² = 176400

x + 100 = 420

Since these are sides, we just consider the positive square root

x + 100 = 420

x = 320m
