Question

Pls someone explain to me how to do these problems and step by step explanation pls

Answer 1

Option 1

Explanation:

This is because in inequalities, the closed circle means greater/less than or equal to and the open circle means greater/less than. Since there is no line under the inequality, it is less than, therefore you need to use an open circle.

Answer 2

option 1 because since it’s less than not less than or equal to, it stays opened. also you follow the direction that the less than sign is pointing towards.
