1. hal_stirrup

? what you want to know???

2. domid24

Is the inequality always, sometimes, or never true

3. Compassionate

7x + 2 ≤ 4x - 8 + 3 7x + 2 ≤ 4x - 5 7x - 4x ≤ - 5 - 2 3x ≤ - 7 7 x ≤ (-)-- 3

4. Compassionate

x = anything less-than or equal-too negative seven over three.

5. Compassionate

@hal_stirrup , I'll return the favor.

6. hal_stirrup

only if you dived by negative number than you reverse the sign!! inequality rule.

7. hal_stirrup

@Compassionate , thanks. kind of you.

8. Compassionate

Only if the 'x' is negative. Example: -3x < -3 = x > 1 On the other hand: 3x < -3 = x < 1, And the other rule: -3x < 3 = x > -1

9. hal_stirrup

sure . thats clear.

guys I'm still confused... is the inequality always, sometimes, or never true?

12. hal_stirrup

well the statement is somewhat not clear so. but this inequality is true.

13. Compassionate

It's sometimes true. Depending on what X is.

14. hal_stirrup

ok

15. Compassionate

10 For example, if x = --- , the statement is not true. 1000

16. hal_stirrup

thanks.

17. hal_stirrup

whats so important to know if the inequality always, sometimes, or never true???

18. domid24

it's my math h.w lolol

19. Compassionate

They can help in real life problems, for example read this: http://www.algebra-class.com/solving-word-problems-in-algebra.html

20. Compassionate
