The commutative property applies only to addition and multiplication of real numbers.
What is commutative property in math?
This law simply states that with addition and multiplication of numbers, you can change the order of the numbers in the problem and it will not affect the answer. Subtraction and division are NOT commutative.
so as ask in question that, does the commutative property apply to all real numbers?
The commutative property applies to addition and multiplication of real numbers, meaning that a + b = b + a and a * b = b * a for any real numbers a and b.
However, it does not apply to subtraction or division, meaning that a - b ≠ b - a and a / b ≠ b / a for all real numbers a and b.
Therefore, the commutative property applies only to addition and multiplication of real numbers.

How many real solutions are there in the quadratic equation?.
The number of real solutions to a quadratic equation depends on the coefficients of the quadratic equation.
A quadratic equation is an equation of the form ax2 + bx + c = 0, where a, b, and c are real numbers. This equation can have either 0, 1, or 2 real solutions. If a is equal to 0, then the equation is not a quadratic equation and can have any number of real solutions.
If the coefficient a is not equal to 0, then the number of real solutions depends on the value of the discriminant, b2 - 4ac. If the discriminant is positive, then there are two real solutions to the equation. If the discriminant is zero, then there is one real solution. If the discriminant is negative, then there are no real solutions.
In summary, a quadratic equation can have 0, 1, or 2 real solutions depending on the value of the discriminant.

Write $a^4 - 3a^2 + 9$ as a product of two monic quadratics with integer coefficients.
$a^4 - 3a^2 + 9$ can be factorised as $(a^2 - 3)(a^2 + 3)$
To factor $a^4 - 3a^2 + 9$ as a product of two monic quadratics with integer coefficients, we can use the difference of squares factorization.
When an expression has the general form a²+2ab+b², then we can factor it as (a+b)². For example, x²+10x+25 can be factored as (x+5)². This method is based on the pattern (a+b)²=a²+2ab+b², which can be verified by expanding the parentheses in (a+b)(a+b).
$a^4 - 3a^2 + 9$ can be factored as $(a^2 - 3)(a^2 + 3)$
Notice that both factors are monic quadratics with integer coefficients.
So, $a^4 - 3a^2 + 9$ = $(a^2 - 3)(a^2 + 3)$

Is the function y 5x 10 linear or nonlinear?.
The y=5x-10 function is nonlinear.
A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0. Although the linear functions are also represented in terms of calculus as well as linear algebra. The only difference is the function notation. Knowing an ordered pair written in function notation is necessary too. f(a) is called a function, where a is an independent variable in which the function is dependent. Linear Function Graph has a straight line whose expression or formula is given by; y = f(x) = px + q
Since you are using y, instead of f(x), I think it's more appropriate to call it a relationship. The equation y=5x-10 describes a set of points that fall on a line, but for it to be a linear function, it should be denoted as f(x)=5x-10.
The distinction isn't so interesting in this case, but how about the case x = y^2? This is a totally valid relationship, but it cannot be a function of x, since a function requires just one output for a given input.
No. If it was a linear function we should have y(λx)=λy(x), ∀x. But that's not what happens. Actually, this function is called an affine function. So, we can see that affine functions are obtained from the linear functions simply by performing a rigid movement.
The linear functions are those that have the form: y=ax.
Therefore, The y=5x-10 function is nonlinear.

How do you solve for range of x?.
Range of x is a way of expressing the set of all possible values for a given variable x.
In order to solve for the range of x, we first need to identify the equation or expression that relates x to other variables. Once we have the equation, we can then solve for the range of x by determining the minimum and maximum possible values for the variable.
For example, if we have the equation x = 3y + 6, we can solve for the range of x by first setting y equal to its minimum and maximum possible values. If we assume y can take values between 0 and 10, then we can solve for the range of x by setting y equal to its minimum (0) and maximum (10) values, respectively.
As we can see in this instance, the x is 6 = x = 36.
In general, to solve for the range of x we need to:
1. Identify the equation or expression that relates x to other variables.
2. Set the other variables to their minimum and maximum possible values.
3. Solve for the minimum and maximum possible values for x.
4. The range of x is the set of all values between the minimum and maximum possible values for x.

Alyson deposits $500 in the bank for 12 years. The bank offers her a 4% interest rate compounded monthly. How much money will be in her account at the end
of the 12 years? (Remember to round your answer to the nearest cent.)
Answer:$917.59
Step-by-step explanation:
The formula for compound interest is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
In this case, the initial deposit is $500, the annual interest rate is 4%, the number of times compounded per year is 12 (monthly), and the number of years is 12.
So, we can plug in the values into the formula:
A = $500(1 + 0.04/12)^(12*12) = $500(1.003333333)^(144) = $500(1.835170816) = $917.585
The final amount in her account after 12 years is $917.58
To round to the nearest cent, we can use the following method:
If the digit in the thousandths place is less than 5, we keep the hundredths digit as is.
If the digit in the thousandths place is greater than 5, we round up the hundredths digit.
In this case the digit in the thousandths is 5 so, we have to round up the hundredths digit of $917.58.
if the simple interest on $5000 for 2 years is $700, then what is the interest rate

Is the number of factor pairs for a number equal to the numbers of a raise for the same number explain
Answer:
yes, for positive numbers
Step-by-step explanation:
You want to know if the number of arrays that represent a number is equal to the number of factor pairs of that number.
AssumptionsWe assume that we're only concerned with Natural numbers (positive integers).
We assume that the factor pair 2×3 is indistinguishable from the factor pair 3×2, and that an array of 2 rows and 3 columns is indistinguishable from an array of 3 rows and 2 columns.
ArraysEach array corresponds to a factor pair. One factor of the pair specifies the number of rows; the other factor specifies the number of columns. The product of those factors is the number of interest.
Example
12 = 1·12 = 2·6 = 3·4 . . . . . factor pairs listed with smallest factor first
The attachment shows arrays associated with these factor pairs.
If the number is a square number, then there will be an odd number of divisors. One of the divisors is repeated to make the factor pair. This results in a square array as one of the arrays that represent the square number. The second attachment shows arrays for the square number 9.
There will be as many arrays as there are factor pairs.

In the figure, angle D measures 31 degrees and angle A measures 27 degrees.
The measurement of angles C and F are 63° and 59° respectively
How to find the measurement of angle B and D?Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles.
In the given image, you notice that angles A, B and C form a right-angled triangle. So the measurement of angle C is 90°. Also, the sum of angles in a triangle is 180°. Thus:
A + B + C = 180°
27° + 90° + C = 180°
117° + C = 180°
C = 180° - 117°
C = 63°
Likewise, angles D, E and F form a right-angled triangle. So the measurement of angle E is 90°. Also, the sum of angles in a triangle is 180°. Thus:
D + E + F = 180°
31° + 90° + F = 180°
121° + F = 180°
F = 180° - 121°
F = 59°
