## vivalakoda 3 years ago Which inequality is graphed? y > |x + 4| – 2 y < |x – 4| – 2 y > |x + 4| + 2 y < |x – 4| + 2

2. andriod09

what is the rule about inequality? do you know it?

3. vivalakoda

No.

4. andriod09

okay, Rule #1: Inequalities that are grater than or equal to, shade up, Rule #2: Inequalities that are less than or equal to shade down. Have you solved any of the equations?

5. vivalakoda

I don't know how :c

6. andriod09

How come you have these problems than?

7. vivalakoda

I do online school. So they just give me random questions

8. andriod09

9. vivalakoda

Unfortunately!

10. andriod09

There is nothing wrong with being homeschooled, except maybe your social life. :] im homwschooled too. lol. anyy wayyy.

11. vivalakoda

Ohhhhhhh. Well I'm not used to it! Lol. I just started this year, it's my like second week. I went to public school all my life so it's a big adjustment.

12. andriod09

same here I am doing the Life of Fred math series, you should try it. :].

13. andriod09

ok, do you know about absolute values?

14. vivalakoda

Yes

15. andriod09

So then make then abosolutes and solve.

16. vivalakoda

Whaaaaaaaaaaaaaaaaaaat Confused

17. andriod09

absolute value = |x+4|

18. vivalakoda

I think I figured it out, I had to set the absolute value to equal zero in which I found the vertex, which is 2, 4

19. andriod09

but when you absolute the vaule, it becomes a positive number, and 0 is neither positive nor negative, :/

20. vivalakoda

That's what my teacher told me to do D:

21. vivalakoda

Wtf

22. jim_thompson5910

The vertex of that given graph is (4,2)

23. jim_thompson5910

The vertex of y = a|x-h| + k is (h,k)

24. andriod09

jim, im a freshman, in honours algebra, and that makes no sense. lol

25. vivalakoda

Algebra 1?

26. jim_thompson5910

y = a|x-h| + k is the general form of an absolute value equation

27. jim_thompson5910

And the vertex is (h,k)

28. jim_thompson5910

Ex: y = a|x-h| + k Let a = 2, h = 3 and k = 5 to get y = 2|x-3|+5 The vertex of y = 2|x-3|+5 is (3,5)
