Question

Which of the following is a solution of y + x < -5?

(-4, -2)
(-3, -2)
(-2, -3)
(-1, -3)

Answer 1

Answer:

FIRST OPTION: (-4, -2)

Step-by-step explanation:

Given the inequality $y + x < -5$, substitute each solution given in the options:

1) For (-4, -2) :

$(-2)+ (-4) < -5$

$-6 < -5$ (This is true)

2) For (-3, -2):

$(-2)+ (-3) < -5$

$-5 < -5$ (This is not true)

3) For (-2, -3):

$(-3)+ (-2) < -5$

$-5 < -5$ (This is not true)

4) For (-1, -3):

$(-3)+ (-1) < -5$

$-4 < -5$ (This is not true)

You can observe that (-4, -2) is a solution of $y + x < -5$

Answer 2

The answer is A.
