Which property is illustrated by the statement.
(2+3.4) + 6 = 2 + (3.4 + 6)
Associative property of addition (i chose this)
Commutative property of multipliction
Inverse property of multiplication
Commutative property of addition
I know its not commutative because there are para thesis and it has to follow a certain order
My Answers were...
1. Associative Property of Addition
2. Rational Numbers
3. 6(x + 4)
4. 1/14

I need help sooo bad I don’t want to fail, my mom will disown me if I lose my b
Yes, you are correct, it shows the associative property of addition.
Isnt this from a test? Does anyone know all the answers or does it change the questions around so theres no cheating....
Not all questions are the same but some are soooo if y'all are havin a hard time at the ones this website doesnt have, you can use:
brainly.com
mathpapa.com/simplify-calculator/
desmos.com/calculator
i used mathpapa for most of it. good luck y'all
We all have different answers so why even use this?????
Hello!
I just got done doing the test and some of the questions were changed a little. So, here are the new answers:
1.Associative property of Addition
2.rational numbers
3.7(y+2)
4. 1/14
5. 3/8
6. 4/81
7. -9
8. (5,28)
9. m=10
10. p=-36
11. b=3
12. {5,6,7,8}
13. x >= 4
14. 7x>= 350; x>=50
15. 52
16. The point where it's at -8 and is going left.
17. the points where they are both closed circles and one of them is at -4 and is going left and another at 4 and is going right.
18. z=4, z=12
19. It's the graph with the points that are positive but bent and not completely straight
20. Decreasing;Linear
21. C(n)=0.90n - 0.40
22. I am not too sure how to explain this one. On my test it was A but it could be different for whomever reading this. So, I suggest looking up mapping diagrams. As #22 is quite easy.
23. yes;6
24. the graph with the lines going upward and are on a positive 3
25. no;y does not vary directly with x.
26. the graph where the line is passing through -6 and positive 3
27. -3
28. -2/7
29. 0
30. y-9=4/5(x-7)
31. y=9/2x+5
32. 2x+3y=-12
33. Neither
34. y=4x+17
35. The graph with the line that is a V shape, going upwards on -1
36. the graph with the point (-2,5)
37. Infinitely many
38. y <= 3
39. 4 days
40. y=3x-2 and y=3x-1
41. (5/4, 61/4)
42. I can't explain this one but I recommend using Desmos graphing Calculator.
43. y <=3x-2 and y>= -4x+2
44. Negative Correlation
45. 0.981
46. 289.3
47. I can't be confident at all; this is about close to a random guess as you can get.
I assure these are all the correct answers for Unit 8 Semester A exam for 2023.
Have a great Christmas, winter, and new years! May God bless you.
