Consider the equation 3x+y=2

Multiply the equation by 3 so that we can eliminate y

3(3x+y=2)=3×2

9x+3y=6

Adding it with 5x−3y=8

9x+3y+5x−3y=6+8

14x=14

x=1

Putting the value of x in equation 3x+y=2

An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language.

A mathematical equation, also known as a statement, shows that two separate expressions are equal. The two expressions are usually connected by the "equal-to" (=) sign. You can find the expressions in a mathematical statement by looking at the left-hand side and the right-hand side of the equation, using the = sign as the point of reference.  

The most popular equations are algebraic equations or expressions, in which letters are used as variables. Variables are placeholders that can assume any value. They can also be referred to as unknowns. You must solve for the correct value of the variable to make the equation true.

Let us look at an example to understand.

4x + 2x = 12

The letter x is the variable. You must find the value of x. Finding this value will make the right-hand side of the equation equal to the left-hand side. Let's solve this together.

In this case, since both variables are the same, you can add the values on the left-hand side.

6x = 12

Now, we divide both sides by the value of '6', which will help us solve for x. Consider this to be a way to unravel the equation. Also, remember that whatever is done to one side must be done to the other.

x = 2

This is exactly how to write an algebraic expression.

The set of vectors spanning the null space of A is {(0,0,z)}.

A set of vectors spanning the null space of a matrix A is a set of vectors that, when multiplied by the matrix A, result in the zero vector. In other words, these vectors are in the null space of A because they are mapped to the zero vector under the transformation represented by A.

To find a set of vectors spanning the null space of matrix A, you can use the following steps:

To find a set of vectors spanning the null space of the matrix A= 1 1 2 -1 2 3 6 -2 -2 1 2 2 0 -2 -4 0:

Write the matrix A in row-reduced echelon form:

1 1 2 | -1

0 0 0 | 0

0 0 0 | 0

The pivot columns are the first and second columns, which contain the leading 1's.

Assign variables x and y to the pivot rows:

1 1 2 | -1

0 0 0 | 0 x

0 0 0 | 0 y

Set the variables corresponding to all other rows in the pivot columns equal to 0:

1 1 2 | -1

0 0 0 | 0 0

0 0 0 | 0 0

Set the variables corresponding to the rows in the non-pivot column equal to a free variable z:

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance. When two quantities are equal, we use the sign "=," and when they are not equal, we use the symbol "," which stands for "not equal." The first value may be greater than (>), less than (<), greater than equal to (>=), or less than equal to (<=) the second value if the two values are not equal.

The words "inequality" and "inequalitas," which mean "unequal, unlike, distinct," and "changeable," respectively, derive from the Old French and Latin, respectively. The magnitude, number, and intensity of two quantities or expressions are compared using this phrase.

There are 333 numbers less than 1000 that are divisible by 3.

To find this, you can divide 1000 by 3 to get 333 with a remainder of 1. Since the numbers less than 1000 that are divisible by 3 do not include 1000, you subtract 1 from 333 to get 332. However, 0 is also divisible by 3, so you should add 1 to 332 to get 333 as the final answer.

When a number divides evenly (i.e., leaves no residue), it is said to be divisible. For instance, since 2 can be divided by 34 equally, 34 may be divided by 2. 34 is not divisible by 3 since doing so would leave us with a remainder.

The interest on Ethan's CD account will be $700 * 1.8% = 12.6$ dollars after one year. Since the CD earns 1.8% interest each year, the interest will be the same amount each year, so the total interest on the CD after 6 years will be $12.6 * 6 = 75.6$ dollars. This means that the CD will be worth $700 + 75.6 = $775.6$ after 6 years.

The quotient is 2x2+5x2+2.

The rational root theorem, also known as the rational root test, is an algebraic theorem that states that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, both the constant term (the term without a variable) and the leading coefficient (the coefficient of the highest power) must be divisible by the fraction's denominator.

Since we have already provided it

[tex]\frac{(6x^2+15x^3+10x^2+10x+4)}{(3x^2+2)}[/tex]

[tex]a_0[/tex] divisions are 1, 2, and 4.

[tex]a_n[/tex] is divided into 1, 2, 3, and 6.

[tex]\displaystyle{x=\dfrac{\pi}{2}n}[/tex] for n is any integers

Step-by-step explanation:

To know the asymptotes, first, we must know values of x that we turn y-value into an undefined value.

We know that:

[tex]\displaystyle{\cot x = \dfrac{1}{\tan x}}[/tex]

Now we have to find value of x that turns the identity above into undefined value, and that is [tex]\displaystyle{x=n\pi}[/tex] where n is any integers. (This gives 1/0 for all x = nπ)

Therefore, a function [tex]\displaystyle{\cot x}[/tex] has asymptote lines at [tex]\displaystyle{x=n \pi}[/tex] for n is integers.

If we consider the given problem:

[tex]\displaystyle{y=\dfrac{1}{3}\cot 2x}[/tex]

We have to find values of x that turn y-value undefined. We know that [tex]\displaystyle{x=n\pi}[/tex] is asymptotes for [tex]\displaystyle{\cot x}[/tex]. Therefore, [tex]\displaystyle{2x=n\pi}[/tex] has to be asymptotes for [tex]\displaystyle{y=\dfrac{1}{3}\cot 2x}[/tex].

Hence, the asymptotes occur at [tex]\displaystyle{x=\dfrac{\pi}{2}n}[/tex] by solving the equation and for n is any integers.
