## ikshjbdckoj maths mind! come in this one!! one year ago one year ago

1. Zelda

And question is?

2. ikshjbdckoj

21. Choose the correct solution graph for the inequality. 12x + 4 ≥ 16 or 3x – 5 ≤ –14 (1 point)

3. Zelda

Attach a picture?

4. mathstudent55

Do you know how to solve an inequality?

10. mathsmind

as for q21 it was the 3rd graph

11. ikshjbdckoj

thank you. I got it :)

12. ikshjbdckoj

13. ikshjbdckoj

|dw:1360195351155:dw|

14. ikshjbdckoj

these drawing right here are for the solve question I put up.

15. mathsmind

for the absolute value question

16. mathsmind

$\left| x-\frac{ 1 }{ 5 } \right|=2$

17. mathsmind

18. mathsmind

11/5 , -9/5

19. ikshjbdckoj

it doesn't have that as a option.

20. mathsmind

oh that is =3 not 2 sorry

21. mathsmind

16/5, -14/5

22. ikshjbdckoj

23. A new book is published and the table shows the number of people who showed up for a book signing in the first, second, third, and fourth month of its release. Which graph could represent the data shown in the table?

23. ikshjbdckoj

mathminds.. look on that microsoft picture i sent you and look at number 23. it has the graph with this qustion im asking.

24. ikshjbdckoj

and here are the answers to number 23.

25. mathsmind

wait i have a call

26. ikshjbdckoj

ok.

27. ikshjbdckoj

28. ikshjbdckoj

29. ikshjbdckoj

30. ikshjbdckoj

31. ikshjbdckoj

I think I got this. I picked the 2nd graph.

32. ikshjbdckoj

Hey mathminds. When you get back on we have to go really fast through this test becasue I have on;y a few hours to complete the rest of this. and i have to get it done!!

33. ikshjbdckoj

24. The table shows the relationship between two variables. Is the relationship a linear function?

34. mathsmind

back sorry that was one of my students

35. ikshjbdckoj

|dw:1360196848549:dw|

36. ikshjbdckoj

yes or no ?

37. mathsmind

its the 2nd graph

38. ikshjbdckoj

that's what I picked. Do you know whether that tableI showed you is linear or not?

39. mathsmind

which question 25

40. ikshjbdckoj

no 24.

41. ikshjbdckoj

do you know which one I'm talking about ?

42. mathsmind

ok let me see

43. ikshjbdckoj

ok

44. mathsmind

yes it is

45. ikshjbdckoj

25. The ordered pairs (1, 5), (2, 25), (3, 125), (4, 625), and (5, 3125) represent a function. What is a rule that represents this function? (1 point)y = x5 y = 5x y = 5x y = x + 5

46. mathsmind

$y=x^5$

47. mathsmind

do u mean that, this is not the answer

48. mathsmind

$y=5^x$

49. mathsmind

50. ikshjbdckoj

|dw:1360197550435:dw|yes I have these as my answers.

51. mathsmind

y=5^x

52. mathsmind

its the first one

53. ikshjbdckoj

26. Suppose noodle soup is on sale for $0.75 a can and you have a coupon for$0.50 off your total purchase. Write a function rule for the cost of n cans of soup. (1 point)C(n) = 0.75n – 0.5 C(n) = 0.5n – 0.75 C(n) = (0.75 + n) – 0.5 C(n) = (0.5 + n) – 0.75

54. mathsmind

when x=1 , 5^1=5 ->(1,5)...

55. ikshjbdckoj

huh??

56. mathsmind

first one

57. ikshjbdckoj

28. Tell whether the sequence is arithmetic. If it is, what is the common difference? –12, –7, –2, 3, . . . (1 point)yes; 5 yes; 8 yes; 3 no

58. mathsmind

0.75n-0.5

59. ikshjbdckoj

44 ikshjbdckoj 028. Tell whether the sequence is arithmetic. If it is, what is the common difference? –12, –7, –2, 3, . . . (1 point)yes; 5 yes; 8 yes; 3 no

60. mathsmind

5

61. mathsmind

look u have to know how to work this out

62. mathsmind

-7-(-12)=5

63. mathsmind

how old are u? which year

64. ikshjbdckoj

I understand how to work out that equation I just have a hard time figuring out how to put it into a equation. and I'm 15. 9th grade.

65. ikshjbdckoj

I have to send a graph with this problem. 29. What is the graph of the function rule? y= |2 x | + 1 (1 point)

66. mathsmind

no don't send the graph

67. ikshjbdckoj

ok

68. ikshjbdckoj

why dont you want me to send the graph?

69. mathsmind

the graph will be V

70. mathsmind

because i can figure the graphs in my head

71. mathsmind

as u can see this is like y=x and y=-x

72. ikshjbdckoj

yes

73. mathsmind

next

74. ikshjbdckoj

I don't know which graph it is though....There are 2 that are going up.

75. mathsmind

ok send the graph

76. ikshjbdckoj

77. mathsmind

next time u do ur work early not in 1 day ok

78. ikshjbdckoj

79. ikshjbdckoj

Yeah I'm definitley gonna do that. This is very frustrating when I wait at the last minute and I don't know how to do anything :(

80. mathsmind

never get to that habit, u have to get rid of it now and thats an order ok

81. ikshjbdckoj

ok

82. mathsmind

when u add +1 it shifts up by 1 unit in y axes

83. ikshjbdckoj

Okay it's very hard for me to understand stuff through typing and texting so is the answer the first graph? cause I think it is.

84. mathsmind

yup

85. ikshjbdckoj

yayyyyyyyy!

86. ikshjbdckoj

30. For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation. x y 3 6 6 18 8 24 (1 point)yes; y = 2x yes; y = 3x yes; y = 4x no; y does not vary directly with x heres the table.|dw:1360198952296:dw|
