5. Rosh007

you posted a huge bunch of question... What you expect us to do??

6. SephI

Can you just tell me the general idea to solving them? Just look at the first one, what is it asking? I just need to know how to do these types of problems.

7. Rosh007

Ok.. I will tell you the method.. In this question. It is asking that you have to find the value of the unknown variable (most probably range of the variable). and by sustituting those range of that value you have to plot the graph

8. SephI

So I would solve the inequality first, right?

9. skullpatrol

Yup

10. Rosh007

Yes... then find the range of the variable

11. SephI

How does one find the range? Can you draw it out?

12. Rosh007

Let us take an example.. first one it self it says \(2x+4\ge24\). so you ned to find the value of x which satisfy this relation

13. Rosh007

How can you find

14. SephI

I would solve for x just like an equation, right?

15. Rosh007

yes..

16. Rosh007

so can you write step by step?

17. SephI

I'll try

18. Rosh007

or just the value of x is sufficient.. I will explan How the range will come after that

19. Rosh007

but step by step is better for you to understand

20. SephI

Can you write it out step by step really fast?

21. Rosh007

I think.... you can use draw tool... Or equation editor

22. Rosh007

If you solve this your own.. you can solve all remaining question by yourself

23. SephI

Okay. Want me to try and solve the first one?

24. Rosh007

I think that is the purpose of Openstudy Yes.. I will Help you, in case of doubts

26. SephI

2x + 4 >/ 24 2x >/ 20 x >/ 10 Now my x will start at ten and go on infinitely?

27. Rosh007

Yes if you got your own.. that is right.. you have done a wonderful job

28. SephI

This is really easy.

29. Rosh007

Yes.. all else is.. but .. You need to take care when dealing with inequality.. some times it may be confusing. to avoid that it is always advisible to chck the answer you got... now substitute any value greater than or equal to 10 and check ...

30. SephI

Ok

31. Rosh007

weather your Left hand side of the equation is greater than or equal to 24... also substitute a value less than 10 to check equation is satisfying or not

32. SephI

Thanks

33. Rosh007

well done.. all the best with next questions too... take care.. think well... once again all the best
