And question is?

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

3. anonymous

Attach a picture?

4. mathstudent55

Do you know how to solve an inequality?

10. anonymous

as for q21 it was the 3rd graph

11. anonymous

thank you. I got it :)

14. anonymous

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

15. anonymous

for the absolute value question

16. anonymous

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

17. anonymous

18. anonymous

11/5 , -9/5

19. anonymous

it doesn't have that as a option.

20. anonymous

oh that is =3 not 2 sorry

21. anonymous

16/5, -14/5

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. anonymous

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

24. anonymous

and here are the answers to number 23.

25. anonymous

wait i have a call

26. anonymous

ok.

31. anonymous

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

32. anonymous

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. anonymous

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

34. anonymous

back sorry that was one of my students

35. anonymous

|dw:1360196848549:dw|

36. anonymous

yes or no ?

37. anonymous

its the 2nd graph

38. anonymous

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

39. anonymous

which question 25

40. anonymous

no 24.

41. anonymous

do you know which one I'm talking about ?

42. anonymous

ok let me see

43. anonymous

ok

44. anonymous

yes it is

45. anonymous

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. anonymous

$y=x^5$

47. anonymous

do u mean that, this is not the answer

48. anonymous

$y=5^x$

49. anonymous

50. anonymous

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

51. anonymous

y=5^x

52. anonymous

its the first one

53. anonymous

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. anonymous

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

55. anonymous

huh??

56. anonymous

first one

57. anonymous

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. anonymous

0.75n-0.5

59. anonymous

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. anonymous

5

61. anonymous

look u have to know how to work this out

62. anonymous

-7-(-12)=5

63. anonymous

how old are u? which year

64. anonymous

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. anonymous

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. anonymous

no don't send the graph

67. anonymous

ok

68. anonymous

why dont you want me to send the graph?

69. anonymous

the graph will be V

70. anonymous

because i can figure the graphs in my head

71. anonymous

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

72. anonymous

yes

73. anonymous

next

74. anonymous

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

75. anonymous

ok send the graph

76. anonymous

77. anonymous

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

78. anonymous

79. anonymous

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. anonymous

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

81. anonymous

ok

82. anonymous

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

83. anonymous

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. anonymous

yup

85. anonymous

yayyyyyyyy!

86. anonymous

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|
