1. NotTim

2. satellite73

pass algebra

3. NotTim

Maybe they wish to achieve greater?

4. newbold_galen

need to graph it

5. NotTim

as separate functions? if so, make a table, then plot the points|dw:1357633118558:dw|

6. NotTim

for both

7. newbold_galen

need to find the point that they will meet t

8. NotTim

by graphing?

9. newbold_galen

no find solutions of x and why the graph it an tell where point it. just need help with the equations

10. NotTim

arrggh

11. NotTim

why not rearrange 1 equation and sub it into the other? You know what I mean?

12. newbold_galen

i know what you mean but i am bad at this and cant get it figured right

13. NotTim

so rearrange y=-x+2 or y=3x-1 to solve for x

14. NotTim

where it becomes x=

15. newbold_galen

so x=2+y ?

16. NotTim

a little off there. forgot something

17. newbold_galen

x=2-y

18. NotTim

yup

19. NotTim

what next?

20. newbold_galen

k and then put that in the 2nd equation right?

21. NotTim

ay

22. newbold_galen

y=3(2-y)-1 --> y=6-3y-1 --> y=5-3y

23. NotTim

what else?

24. newbold_galen

stumped after that

25. NotTim

their are 2 y-variables still

26. newbold_galen

oh so add 1 y too each side?

27. newbold_galen

well 3 y

28. NotTim

ay

29. newbold_galen

so 4y=5 ?

30. newbold_galen

then divide both sides by 4 right?

31. NotTim

ay

32. newbold_galen

so then how do i put that in to figure x?

33. NotTim

y=?

34. NotTim

sub the value for whatever valeu you found into 1 of the equations

35. newbold_galen

5/4 or 1.25

36. NotTim

ok. sub that value as y into one of the equations

37. newbold_galen

x=.75?

38. NotTim

i have no idea. didnt do the math.

39. newbold_galen

oh ok

40. newbold_galen

well thank you so much . u were a huge help. might finally be getting this

41. NotTim

well, good luck to you. that's all you need for this question then?

42. newbold_galen

yep. can graph from that

43. NotTim

awesome. NOTTIM AWAY
