Question

What is the solution to the inequality + 4 ≤ 0? (–∞, –28) (–∞, –28] (28, ∞) [28, ∞)

Answer 1

The Inequality is

y +4 ≤ 0

Adding -4 , on both sides

y +4-4≤ 0-4

y≤-4

Which can be Written as , [-∞, -4]

And also,can be Written as y is the set of all real numbers less than or equal to -4.

Answer 2

`(-\infty,-28`]

Explanation:

We are given that an inequality

`y+4\leq 0`

We have to find the solution of given inequality.

Subtract 4 on both sides of inequality

`y+4-4\leq 0-4`

`y\leq -4`

`y\in(-\infty, -4`]

Therefore, solution set of given inequality is given by (-
`\infty,-4`].

Answer:
`(-\infty,-28`]
