Question

Okay so I'm working on this assignment and I see this question and I'm very confused, aren't the first 2 answers the same and the next 2 are? I am very confused...

Answer 1

No

Explanation:

The first and 2nd answer are different because in the first one the circle is open and in the 2nd one the circle is closed. When the circle is open it means that the number that the circle is on is not a part of the asnwer. This is represented by < or > signs. When the circle is closed it means the number is included in the answer. This is represented by the
`\leq or \geq` symbol.

Answer 2

actually no.

Explanation:

I assume you know the 4 inequalites:

The 4 Inequalities

Symbol Words Example

> greater than x+3 > 2

< less than 7x < 28

≥ greater than or equal to 5 ≥ x−1

≤ less than or equal to 2y+1 ≤ 7

The "open circle" represents less than or greater than, and the "closed circle" represents greater than or equal to or less than or equal to.

Hope it helps! Have a great day! :) let me know if it helped
