Math Problem Statement

Which graph represents the solution set of this inequality?

[\qquad-11-2d \geq 1]

Choose 1 answer:

Choose 1 answer:

(Choice A)   

A

(Choice B)   

B

(Choice C)   

C

(Choice D)   

D

Solution

Let's solve the inequality first:

112d1-11 - 2d \geq 1

Step 1: Add 11 to both sides

2d1+11-2d \geq 1 + 11

2d12-2d \geq 12

Step 2: Divide both sides by -2

When dividing by a negative number, remember to reverse the inequality sign:

d122d \leq \frac{12}{-2}

d6d \leq -6

So, the solution to the inequality is d6d \leq -6.

Interpreting the Graphs

On a number line, this solution is represented by an arrow starting at 6-6 with a filled circle (since the inequality is \leq) pointing to the left.

Without specific descriptions of the answer choices (A, B, C, D) like before, I can't point to the exact answer graphically. However, you should look for the graph that has a filled circle at 6-6 and an arrow pointing to the left.


Would you like further details or have any questions?

Here are some related questions:

  1. How would the graph change if the inequality was d<6d < -6?
  2. What if the inequality was d6d \geq -6? How would the graph look?
  3. How do you represent the inequality d>6d > -6 on a number line?
  4. Can you explain why the inequality sign flips when dividing by a negative number?
  5. What happens to the solution if the original inequality was 11+2d1-11 + 2d \geq 1 instead?

Tip: Always keep in mind to reverse the inequality sign when dividing or multiplying both sides by a negative number!
