Answer: D) Full circle on -2 and arrow pointing to the right.

Step-by-step explanation:

-\frac{5}{2}x -3\leq 2

add 3

-\frac{5}{2}x \leq 2+3

-\frac{5}{2}x \leq 5

multiply by the negative reciprocal of the fraction. (<u>NOTE:</u> When multiplying or dividing by negative numbers, the inequality sign flips.)

(-\frac{2}{5}) -\frac{5}{2}x \leq 5(-\frac{2}{5})

x\geq -2

This tells us that x has to be greater than or equal to -2
