Answer:

D

Explanation:

Remember how absolute values turn everything inside of it into a positive number? Like |-4|=4 and |4|=4 as well.

Well, it works the same for equations.

When you have an absolute value equation like this, you have to split it into two parts.

The positive version

| d-3.5 | ≤ 1.5

and the negative version

|-(d-3.5)| ≤ 1.5

solve for the value of d in both equation.

Remember that you have to flip the inequality sign when dividing or multiplying by a negative number

I assume you know how to graph the inequality once you get the value for d.

d≤5 and d≥2

so

2 ≤ d ≤ 5

meaning d is between 2 and 5.
