The commutative property for addition just means the sum is the same no matter what order you add the terms. This property is also true for multiplication of real numbers.
If altering the operands' order has no effect on the outcome, the binary operation is commutative in mathematics. Numerous binary operations depend on it as a fundamental property, and numerous mathematical arguments.
A commutative property in mathematics states that if integer positions are switched around or combined while performing addition or multiplication operations, the result will remain the same.
According to the commutative property, the numbers we use can be moved around or swapped around without changing the solution. For addition and multiplication, the property is true, but not for division or subtraction.

2. On a day in December the temperature is 5°C at noon. A cold front is coming in and the
temperature is dropping by 2°C every hour. What time will it be when the temperature is
-14°C℃?
Answer:
9:30 p.m.
Step-by-step explanation:
Starting at noon (12:00 p.m.) the temperature is 5 degrees Celsius and drops 2 degrees every hour. In the attached image I have drawn it out to better see it.
Starting at noon and subtracting 2 every hour gives us…
12:00=5
1:00 = 3
2:00 = 1
3:00 = -1
(And so on until we get)
9:00= -13 degrees
So how do we get to 14 if it is dropping 2 degrees an hour? Simple! How much does it drop every half hour? 1 degrees! So for ever 30 minutes the temperature drops 1 degrees.
This means that at 9:30 the temperature will be -14 degrees Celsius.

Se vende un terreno de 540 000 m2 a tres socios, de modo que el
primero paga las 3/5 del precio, el segundo la tercera parte y el tercero el
resto.
a) ¿Cuánto terreno corresponde a cada socio?
b) ¿Qué fracción del total le correspondió al último?
El primer socio adquirió un terreno de 324 000 metros cuadrados, el segundo socio un terreno de 180 000 metros cuadrados y el tercer socio un terreno de 36 000 metros cuadrados. Al tercer socio le corresponde la fracción de 1 / 15 de todo el terreno.
¿Cuánto del terreno y su precio corresponde a cada socio?
Tenemos que el precio es directamente proprocional a la extensión del terreno, de modo que cada socio tiene una participación en el terreno. a) Entonces la participación de cada persona es la siguiente:
Primer socio
x = (3 / 5) · (540 000)
x = 324 000
Segundo socio
x = (1 / 3) · (540 000)
x = 180 000
Tercer socio
x = (1 - 3 / 5 - 1 / 3) · (540 000)
x = 36 000
b) Y la fracción del total correspondiente al tercer socio es:

A right triangle is formed in the first quadrant by the x- and y-axes and a line through the point (3, 2). write the length l of the hypotenuse as a function of x.
The length l of the hypotenuse as function of x is l = [tex]\sqrt{\frac{4x^{2} }{(x-3)^{2} }+x^{2} }[/tex]
Given,
A right triangle is formed in the first quadrant by x and y axes and a line through the point (3, 2).
The length of sides of triangle are y and x.
By Pythagoras theorem, the length of the hypotenuse is:
l = [tex]\sqrt{y^{2}+x^{2} }[/tex]
Now, we can choose two points to get the value of slope (x₁, y₁) = (3, 2) and (x₂, y₂) = (x, 0)
By using the formula, we get the slope:
m = [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex] = [tex]\frac{0-2}{x-3}[/tex] = [tex]-\frac{2}{x-3}[/tex]
The slope is same when passing through (x, 0) and (0, y) because its in the same line.
m = [tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex] = [tex]\frac{y-0}{0-x}[/tex] = [tex]\frac{y}{-x}[/tex]
That is, m = [tex]-\frac{y}{x}[/tex]
These slopes are equal. So, we can equate them,
[tex]-\frac{2}{x-3}[/tex] = [tex]-\frac{y}{x}[/tex]
[tex]-\frac{2(-x)}{x-3}[/tex] = y
y = [tex]\frac{2x}{x-3}[/tex]
Substitute this to the equation,
l = [tex]\sqrt{y^{2} +x^{2} }[/tex]
l = [tex]\sqrt{(\frac{2x}{x-3})^{2} +x^{2} }[/tex]
l = [tex]\sqrt{\frac{4x^{2} }{(x-3)^{2} } +x^{2} }[/tex]
That is, the hypotenuse has a length of
l = [tex]\sqrt{\frac{4x^{2} }{(x-3)^{2} } +x^{2} }[/tex]

Select EACH correct answer.
A, B, C OR D
1) The graph that best models the situation is; Graph A
2) The expression that describes the end behaviors of the function modeled by the graph is; As x increases without bound, f(x) approaches the line y = 0
How to Interpret Quadratic Graphs?
We are told that Hugh wants to start a workout program. Sinmce he starts with running three times a week, we can liken this to the y-intercept. Thus; y-intercept = 3
Now, we are told that he increases the running per week by 17%. This means that the slope of the graph will be 17% or 0.17.
Looking at the given graphs, only graphs A and B have their y-intercepts at y = 3.
Now, looking at both graphs, the one with slope closest to 17% will be graph A.
2) The expressions describe the end behaviors of the function modeled by the graph is; D: As x increases without bound, f(x) approaches the line y = 0

Hey 132 inch board is cut into two pieces one piece is three times the length of the other piece find the length for the short piece
The length of the shorter piece is 33 inches.
132 inches of the board is cut into 2 pieces. The board is divided into 2 parts.
One piece is three times the length of the other.
let ,one piece = x
The other piece = 3x
The length(x) of the shorter part can be found below
x + 3x = 132
4x = 132
divide both sides by 4
x = 132 / 4
x = 33
Therefore the length of the shorter piece is 33 inches.

The mean of six rational numbers is -4.3.
a) What is the sum of the rational numbers?
b) If five of the numbers each equal -4.5,
what is the sixth number?
Answer:
Step-by-step explanation:
a) You can calculate by multiplying the decimal numbers-
4.3 x 6 = -25.8
-25.8 = The sum of the rational numbers
b) You multiply -4.5 by 5 to get the sum of the first 5 numbers-
-4.5 x 5 = -22.5a
Then you subtract -22.5 from -25.8
-25.8 - (-22.5) = -3.3 --------------- -25.8 + 22.5 = -3.3
So, the sixth number is -3.3

The probability that a camper entering the Luray Caverns has Canadian license plates is 0.3214.
A = a vehicle entering the Luray caverns has Canadian license plates
B = it is a camper
P(A) = 0.12
P(B) = 0.28
P(A∩B) = 0.09
P(A|B) = P(A∩B) / P(B)
P(A|B) = 0.09 / 0.28
P(A|B) = 0.3214

how do you find the zeros of polynomial r^2-28=-3x? Please show steps as I do not understand how to solve this problem. Thank you ^-^
Answer:
x = -7 and x = 4
Step-by-step explanation:
Note, I am taking the polynomial equation as
[tex]x^2 - 28 = -3x[/tex]
Otherwise it does not become a polynomial of one variable and cannot be solved
Zeros of a polynomial are the values of x where the polynomial value itself is 0
Standard equation for a polynomial of degree 2 is ax² + bx + c = 0 where a, b and c are constants
Degree is the highest exponent. Here the highest exponent is 2 so the polynomial has degree 2. Such a polynomial is called a quadratic polynomial
So we first have to convert
x² - 28 = - 3x into this form ax² + bx + c
1. Add 3x to both sides
x² - 28 + 3x = -3x + 3x =0
==> x² + 3x - 28 = 0
With a = 1, b = 3 and c = -28
2. Factor x² + 3x - 28 = 0
Here a = 1, b = 3 and c = -28
Factoring means find two expressions x+a and x +b such that (x + a) (x + b) = x² + 3x - 28 = 0
Then we can state that
x + a = 0 ==> x = -a as one solution
x + b = 0 ==> x = -b as the other solution
To factor, find two numbers m and n(could be negative) such that mn = c and m + n = b
28 has factors 7 and 4 so that is a good start
-28 = -7 x 4 or could also be 7 x -4
How do we choose?
Add both and see what gives you +3
-7 + 4 = -3 Nope
7 + -4 = 7-4 = 3 YES
So the factors are 7 and -4
(x + m) = (x + 7)
(x + n) = (x -4)
So the original quadratic polynomial becomes
(x + 7)(x -4) =
This means
x + 7 = 0 ==> x = -7
x - 4 = 0 ==> x = 4
So the solutions(also called roots) of x² + 3x - 28 = 0 are:
x = -7 and x = 4
Both the above values satisfy the quadratic equation

The inverse for the function f (x) = 1 / 5 x³ will be f ⁻¹ (x) = ∛ (5 x).
We are given the function:
f (x) = 1 / 5 x³
we need to find the inverse of the function.
First we will write the function in the form of x.
y = 1 / 5 x³
5 y = x³
x³ = 5 y
x = ∛ (5 y)
So, the inverse function will be:
f ⁻¹ (x) = ∛ (5 x)
