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

Answer:

Option C - 2(-5)+2(3) ; -4

Step-by-step explanation:

Distributive property means breaking up the factors and multiplying them separately

So here we have 2(-5+3) = 2(-5)+2(3) = (-10)+(6) = (-4)

So (-4) is the value.

Hope this helps you.
