Mathematics
1 answer:
mote1985 [20]3 years ago
3 0

Answer: 6, 12

-x+y=6    [eq.1]

2x + y = - 12    [eq.2]

    [eq.2] - [eq.1]

2x + y - (-x) - y = - 12 - 6

2x +x =-18

3x=18

x = 18/3

ans: x = 6

substituting x=6 in [eq.1]

-x + y = 6

-6 +y =6

ans: y= 12

Help please will mark brainliest!!!
Daniel [21]

Answer:

45°

Step-by-step explanation:

Well, compared to 90°, it looks like it's just smaller, but not too small. It couldn't be 15° degrees, or 60°, as it was probably too much. I Don't think it's 30° either,  because it looked bigger than what a 30° angle would be.

Hope it helped!

3(2c-8) - 10c > 0 can some one explain how to solve this ?​
Jet001 [13]

Answer:

c < - 6

Step-by-step explanation:

Given

3(2c - 8) - 10c > 0 ← distribute and simplify left side

6c - 24 - 10c > 0

- 4c - 24 > 0 ( add 24 to both sides )

- 4c > 24

Divide both sides by - 4, reversing the inequality symbol as a consequence of dividing by a negative quantity.

c < - 6
