Step-by-step explanation:

12+3n=-3

3n=-15

n=-5

First, you subtract 12 from both sides of the equation. Now, you should have 3n=-15. Next, you divide 3 on both sides of the equation to get your answer of n=-5

Answer:

y =  -  \frac{1}{4} x - 10

Step-by-step explanation:

The negative reciprocal of 4 is -1/4.

Let's substitute in our values, to find the y-intercept:

y =  -  \frac{1}{4} x + c

- 11 =  - 1 + c

c =  - 10

Finally, our full equation is:

y =  -  \frac{1}{4} x - 10

8 > 3 (true)

x - y > 1

5 - (-2) >1

5 + 2 > 1

7 > 1 (True)

For 0,5

2x + y > 3

2(0) + (5) > 3

0 + 5 > 3

5 > 3 (true)

x - y > 1

0 - (5) >1

-5 > 1

--5 > 1 (false)
