Answer:

A

Step-by-step explanation:

9-4d ≥ -3

Subtract 9 from each side

9-9-4d ≥ -3-9

-4d ≥ -12

Divide each side by -4, remembering to flip the inequality

-4d/-4≤-12/-4

d ≤3

There is a closed circle at 3 and the line goes to the left

First, solve for the variable.

Note: When dividing or multiplying an inequality by a negative number, the inequality sign must be switched.

Given:

9 - 4d ≥ -3

Subtract 9:

-4d ≥ -12

Divide by -4:

d ≤ 3

This means that the solution is less than or equal to 3.

Option A shows d ≤ 3

Option B shows d ≥ 3

Option C shows d < 3

Option D shows d > -3

A
