What is the solution to the inequality StartFraction d Over 7 EndFraction + 4 ≤ 0? (–[infinity], –28) (–[infinity], –28] (28, [infinity]) [28, [infinity])

Answer :

Answer:

(B)[tex](-\infty, -28][/tex]

Step-by-step explanation:

Given the inequality:[tex]\frac{d}{7}+4\leq 0[/tex]

[tex]\dfrac{d}{7}+4\leq 0\\$Subtract 4 from both sides\\\dfrac{d}{7}+4-4\leq 0-4\\\dfrac{d}{7}\leq -4\\$Multiply both sides by 7\\\dfrac{d}{7}*7\leq -4*7\\d\leq-28[/tex]

Therefore, the solution to the inequality is: [tex](-\infty, -28][/tex].

The correct option is B.
