1. ## Need Help With Some Questions

Hello , Can anyone help me with those questions and explanations please ;(

First one is : Find the equation of the circle with centre (-2,3) that passes through (1,-1).

Second is : Find which values of x satisfy the following , 1/2-x<2

3. Express the following as either open or closed intervals
{x: |x-4|≤ 6}

4. Express the following intervals in the form { x: | ax + b | < c } or { x: | ax + b | ≤ c }

(-4,-2)

2. Hello and welcome to MathHelpForum.
You should understand that this is not a homework service nor is it a tutorial service.
PLease either post some of your own work on this problem or explain what you do not understand about the question.

3. I want to understand whats written up in the thread , and for your knowledge this is not homework thats for me to understand

4. You missed the point completely.
We cannot help if we do not know what you do not understand.
None of us here is a mind reader.

5. i dont understand anything

In that case you did not read my first post carefully.

You need to hire a tutor.

7. Seriously then why is the site called mathhelpforum.

8. The word help implies correction to misunderstandings.
You want to be taught this material.
We do not do that.

Moderator edit: MHF stands for Math Help Forum. MHF helps students with specific questions. MHF does not teach course material, that is the job of the student's instructor or a tutor.

There is a reasonable assumption that a student understands something about the material the question relates to and can show some work or say specifically where s/he is stuck with the question. If a student understands nothing, then that student requires more than MHF can provide.
