Answer 1

On Inequalities there’s a shaded circle and a not shaded circle what do they mean?

you have to remember that inequalities have an equal or not equal part.

if the sign is (end point not part of the answer)

greater than >

less than <

the point is open (not shaded) the end point is not part of the inequality.

If the sign is (end point part of the answer)

Equal =

Greater than equal to ≥

Less than equal to ≤

The point is solid.

Hope this helps.
