Answer:
The solution to the inequality is (–∞, –28]
Option B is correct.
Step-by-step explanation:
Given the inequality
[tex]\frac{d}{7}+4\leq 0[/tex]
We have to find the solution to the inequality.
[tex]Inequality:\frac{d}{7}+4\leq 0[/tex]
Subtracting 4 both sides
[tex]\frac{d}{7} \leq 0-4[/tex]
[tex]\frac{d}{7} \leq -4[/tex]
Multiply by 7 both sides
[tex]d\leq 7\times -4=-28[/tex]
[tex]d\leq -28[/tex]
Hence, the solution of d is the values less than equals to -28 i.e
(–∞, –28]
Option B is correct.
