Answer:
Step-by-step explanation:
G. 10x3=3x10 1. Commutative property of multiplication
3. Associative property of Addition
F. (5x3)x4=5x(3x4) 4.Associative property of multiplication
J. If 11 = y then y = 11 5. Symmetric property
A. 21=21 6. Reflexive property
7. Transitive property
8. Zero property of multiplication
9. multiplicative inverse
D. 9x0=0 10. Zero property of multiplication
E. 4+0=4 11. Additive identity
H. 19x1=19 12. Multiplicative identity
B. If k=15 and 5 = 3m. Then k = 3m This statement is not true.
This may be the transitive property, but this was written incorrectly. You have 15 in k = 15, but 5 in 5 = 3m.
C. 7+4=4+7 This is commutative property of addition, which is not listed above
I. 8x1/2=1 This statement is false. Maybe you meant 8 x 1/8 = 1. Then it is 9. Multiplicative inverse.
K. (6+2) + 1 = 6 + 2 + 1 This does not illustrate anything.
Maybe you missed the parentheses on the right side: 6 + (2 + 1). Then it is the associative property of addition.
L. 2+(2-)=0 If this were 2 + (-2) = 0, then it would be Additive Inverse, but I don't see this listed above.

Answer:
y = - 3x - 3Step-by-step explanation:
Given table:
x | -2, 2, 6, 10 y | 3, -9, -21, -33Use two pairs of points to work out the equation of the line y = mx + b:
(-2, 3) and (2, - 9)Find the slope:
m = (-9 - 3)/(2 - (-2)) = - 12/4 = - 3Use one pair to find the y-intercept:
3 = - 3*(-2) + b3 = 6 + bb = 3 - 6b = - 3The line is:
y = - 3x - 3m = (-9 - 3)/(2 + 2) = -12/4 = -3 ==> (x)
3 = (-3)•(-2) + b
3 = 3•2 + b
3 = 6 + b
b = -3 ==> (a)
Soo :
y = -3x - 32p+3q=-7
3p+5q=-12
What is the solution in an ordered pair?
Answer:
(p, q ) = (1, - 3 )
Step-by-step explanation:
2p + 3q = - 7 → (1)
3p + 5q = - 12 → (2)
Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate p
6p + 9q = - 21 → (3)
- 6p - 10q = 24 → (4)
Add (3) and (4) term by term to eliminate p
0 - q = 3
-q = 3 ( multiply both sides by - 1 )
q = - 3
Substitute q = - 3 into either of the 2 equations and solve for p
Substituting into (1)
2p + 3(- 3) = - 7
2p - 9 = - 7 ( add 9 to both sides )
2p = 2 ( divide both sides by 2 )
p = 1

Answering part A:
5x + -3x 7y + 3y + 2y 4xy doesn't have a like term
Step-by-step explanation:
like terms are when in an equation they might have variables that match like 4y + 7y they have the same variable which is y or 6 + 7 they don't have a variable at all but they are similar in that way. Btw why it says -3x is because I changed the equation to be all addition so I did kcc you don't have to do that if you find a different solution :) anyway lets move on to part b
Answering part B:

Answer:
0,01
Step-by-step explanation:
0,0001 = 1 / 10000
√0,0001
= √( 1 / 10000 )
= √1 / √10000
= 1 / 100
= 0,01
The Western inventory was written by 4 different authors. Author A wrote 1/4 of the books, author b wrote 5/16 of the books, and author c write 3/8 of the books. What part of the inventory did author D write?
Answer:
Author D write 1/16 of the total number of books.
Step-by-step explanation:
Let the total number of books be b. Then the amounts written by the four authors would be represented by:
(1/4)A
(5/16)A
(3/8)A
( ? )A
Add these together, realizing that the LCD here is 16:
(4/16)A
(5/16)A
(6/16)A
( ? ) A
------------
(15/16)A must then equal the remainder of the work: (16/16)A
Thus, Author D wrote (1/16)A of the books. (Note that 4/16 + 5/16 + 6/16 + 1/16 = 1)
Author D write 1/16 of the total number of books.

Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = 4/3x - 3
Step-by-step explanation:
1. Find two pints on the line: ((3,1) and (6, 5).
2. Find the slope: Slope = (change in y-values)/(change in the x-values).
Slope = (5 - 1)/(6 - 3) = 4/3
3. Use the slope and one point and substitute into y = mx + b to solve for "b"
y = mx + b slope = 4/3 and point (3, 1)
1 = 4/3(3) + b 4/3 · 3/1 = 12/3 = 4
1 = 4 + b
1 - 4 = b
-3 = b
4. Write the equation of the line: m = 4/3 and b = -3 Substitute into y = mx + b
y = 4/3x - 3
2. A trader received a commission of 25 percent on the sales he made in a month. His commission was CH¢ 180.00. find his total sales for a month.
Answer:
CH¢ 720.00Step-by-step explanation:
25% commission equals 180.00
Total sales amount is x:
x*25/100 = 1800.25x = 180x = 180/0.25x = 720What is the average rate of change of the function f(x)=4x^2+3x on the interval [1,5]
Answer:
7, though I don't know if it's 100% correct. I tried to help.
Step-by-step explanation:
f(x) = 4x^2 + 3x interval [1,5]
f(1) = 4(1)^2 + 3(1)
f(1) = 4 + 3
f(1) = 7
Answer:
[tex]\boxed {\boxed {\sf 27}}[/tex]
Step-by-step explanation:
The average rate of change is the change in the output from one input to another. Essentially, it is the change in y over the change in x.
[tex]\frac {\Delta y}{\Delta x} = \frac { f (x_2)- f(x_1) }{x_2-x_1}[/tex]
Let's assign 1 to x₁ and 5 to x₂.
[tex]\frac {f(5)-f(1)}{5-1}[/tex]
We must find the outputs f(5) and f(1). Substitute the value in for each x in the function.
f(x)= 4x² + 3x
f(5) = 4(5)² + 3(5) f(5)= 4(25) + 15 f(5) = 100 + 15 =115f(1)= 4(1)² + 3(1) f(1)= 4(1) + 3 f(1)= 4+ 3 =7
Now we can find the average rate of change. We know the outputs and we know the inputs.
[tex]\frac {f(5)-f(1)}{5-1}[/tex]
[tex]\frac {115 -7}{5-1}[/tex]
[tex]\frac {108}{4}[/tex]
[tex]27[/tex]
The average of change of the function f(x) = 4x² + 3x on the interval [1,5] is 27.

If the probability that the Islanders will beat the Rangers in a game is 5/6, what is the probability that the Islanders will win at most two out of five games in a series against the Rangers? Round your answer to the nearest thousandth.
Answer:
The chance that the Islanders will win n games out of 6 is:
0.47 ^ n + (1 - 0.47) ^ (6 - n) * 6! / n! / (6 - n!)
So, the chance of winning 4 games is 0.205605
the chance of winning 5 games is 0.072932
the chance of winning all 6 games is 0.010779
Adding these together we get 0.289316
Rounding to the nearest thousandth we get 0.289 (or 28.9%)

1/8 x^3 - 1/27 y^3
Answer:
(3x-2y)(9x²+6xy+4y²)/216
Step-by-step explanation:
Simplify:
M = 4/9 + 11/72
N = 8/15 - 1/3
O = 8/7 + 9/35
P = 3 - 2/10
Q = 11/15 + 1/6
R = 3/4 - 7/10
Step-by-step explanation:
M = 4/9 + 11/72
M = (4 x 8) / (9 x 8) + 11/72
M = 32/72 + 11/72
M = 43/72
N = 8/15 - 1/3
N = 8/15 - (1 x 5) / (3 x 5)
N = 8/15 - 5/15
N = 3/15
N = (3 x 1) / (3 x 5)
N = 1/5
O = 8/7 + 9/35
O = (8 x 5) / (7 x 5) + 9/35
O = 40/35 + 9/35
O = 49/35
O = (7 x 7) / (7 x 5)
O = 7/5
P = 3 - 2/10
P = (3 x 10) / (1 x 10) - 2/10
P = 30/10 - 2/10
P = 28/10
P = (2 x 14) / (2 x 5)
P = 14/5
Q = 11/15 + 1/6
Q = (11 x 2) / (15 x 2) + (1 x 5) / (6 x 5)
Q = 22/30 + 5/30
Q = 27/30
Q = (3 x 9) / (3 x 10)
Q = 9/10
R = 3/4 - 7/10
R = (3 x 5) / (4 x 5) - (7 x 2) / (10 x 2)
R = 15/20 - 14/20
R = 1/20.
