whats the 2nd equation ?

5. hartnn

just type instead of drawing :P

10. hartnn

x>-2|dw:1355995605154:dw|

11. koda10

(-1, 6)

12. koda10

so

13. koda10

(-1, 6)

14. hartnn

what is -1,6 ?? you would have a region as solution, right ? not a point....

15. koda10

-(3, -1)

16. koda10

(-3, -1)

|dw:1355995967893:dw| thats looks so shabby :P

19. koda10

(1, 11)

20. hartnn

do u have choices/options ?

21. koda10

(-1, 6) (1, 11) (-1, 4) (-3, -1)

22. hartnn

ok, x>-2, so D is out

23. koda10

(1, 11)

25. hartnn

wait, 11<2+7 this is false. so not 1,11

26. koda10

Graph each system of inequalities. Then use your graph to identify a solution to the system. 2x - 5y > 0 x - 4y > -8 (Points : 1) (28, 9) (28, 16) (32, 10) (32, 8)

27. koda10

(-1, 4)

28. hartnn

4< -2+7 is true, so yes

29. koda10

Graph each system of inequalities. Then use your graph to identify a solution to the system. 2x - 5y > 0 x- 4y >- 8 (Points : 1) (28, 9) (28, 16) (32, 10) (32, 8)

30. koda10

(32, 8)

31. hartnn

yes.

can't open

34. koda10

Select the system of linear inequalities whose solution is graphed. (Points : 1) y > 3x - 1; x + 3y < 6 y 3x- 1; x + 3y 6 y < 3x - 1; x + 3y > 6 y > 3x - 1; x + 3y 6

35. koda10
36. hartnn

that links doesn't work for me

37. koda10

y > 3x - 1; x + 3y < 6 y< 3x- 1; x + 3y > 6 y < 3x - 1; x + 3y > 6 y > 3x - 1; x + 3y <6

38. hartnn

can't open that link so can't help
