Question

Who ever answer this is a god

Answer 1

Answer:

(-5,-1), (-1, -2), (-6,0)

Step-by-step explanation:

You can just plug in the answers to see which ones are correct.

x + 3y >_-8

-5 -3 = -8

0 -9 = -9

-1 - 6 = -7

-6 -0 = -6

-16 -6 = -10

Answers are all ones that are greater than or equal to -8

Answers = (-5,-1), (-1, -2), (-6,0)

Answer 2

Answer:

option (3) and (4) are correct.

Step-by-step explanation:

We are given an inequality x + 3y ≥ -8

To check out of given ordered pair which satisfies the above inequality ,

Consider each point and we put them in the given inequality if they satisfy it they are solution  to the given equation.

1) (-5, -1)

Substitute x = -5 and y = -1 in x + 3y ≥ -8 We get,

x + 3y ≥ -8 ⇒  (-5)+ 3(-1) ≥ -8  ⇒  (-5) - 3 ≥ -8  ⇒  -9  ≥ -8 (not true) as -8 ≥ -9

2) (0, -3)

Substitute x = 0 and y = -3 in x + 3y ≥ -8 We get,

x + 3y ≥ -8 ⇒  (0)+ 3(-3) ≥ -8  ⇒  - 9 ≥ -8  (not true) as -8 ≥ -9

3) (-1, -2)

Substitute x = -1 and y = -2 in x + 3y ≥ -8 We get,

x + 3y ≥ -8 ⇒  (-1)+ 3(-2) ≥ -8  ⇒  (-1) - 6 ≥ -8  ⇒  -7  ≥ -8 (true).

4) (-6, 0)

Substitute x = -6 and y = 0 in x + 3y ≥ -8 We get,

x + 3y ≥ -8 ⇒  (-6)+ 3(0) ≥ -8  ⇒  (-6)  ≥ -8  (true)

5) (-16, 2)

Substitute x = -16 and y = 2 in x + 3y ≥ -8 We get,

x + 3y ≥ -8 ⇒  (-16)+ 3(2) ≥ -8  ⇒ (-16) +6 ≥ -8  ⇒  -10  ≥ -8 (not true) as -8 ≥ -10

Hence, only  (-1, -2) and (-6, 0) is correct.

Thus, option (3) and (4) are correct.
