Question

What is the solution to the inequality d/7+ 4 ≤ 0?

(–∞, –28)
(–∞, –28]
(28, ∞)
[28, ∞)

Answer 1

28, infinite

Explanation:

Answer 2

The solution to the inequality is (–∞, –28]

Option B is correct.

Explanation:

Given the inequality

`(d)/(7)+4\leq 0`

We have to find the solution to the inequality.

`Inequality:(d)/(7)+4\leq 0`

Subtracting 4 both sides

`(d)/(7) \leq 0-4`

`(d)/(7) \leq -4`

Multiply by 7 both sides

`d\leq 7* -4=-28`

`d\leq -28`

Hence, the solution of d is the values less than equals to -28 i.e

(–∞, –28]

Option B is correct.
