Which equation can pair with x – y = –2 to create a consistent and dependent system? 6x + 2y = 15 –3x + 3y = 6 –8x – 3y = 2 4x – 4y = 6?

Answer

–3x + 3y = 6

Explanation

We need to simplify each expression to see which one is similar to  x – y = –2.

–3x + 3y = 6

multiply by 1/3 on both sides.

1/3( –3x + 3y) = 6 × 1/3

 ⇒   -x + y = 2

Multiply by -1 on both sides.

-1( –x + y) = 2 ×-1

⇒ x - y = -2

–3x + 3y = 6

Step-by-step explanation:

3 is greater then both of those numbers

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
