How do you solve an algebraic equation with 3 variables?.

To solve the equation 6 - square root of x-2 = x + 4, you can follow these steps:

Start by isolating the square root term on one side of the equation. Subtract x + 4 from both sides to get:

6 - x - 4 - square root of x-2 = 0

Next, combine like terms:

2 - square root of x-2 = 0

Add square root of x-2 to both sides to get:

2 = square root of x-2

Now square both sides of the equation:

4 = x - 2

Finally, add 2 to both sides:

x = 6

So the solution is x = 6

Answer:

d = 63 degree

e = 96 degree

f = 21 degrees

Step-by-step explanation:

The angle d is the vertical angle theorem with 63 degrees; that is why d is 63 degrees.

The angle e is the vertical angle theorem with 96 degrees; that is why d is 63 degrees.

96 + 63 = 159 degrees

180 - 159 = 21 degrees

So, f = 21 degrees

By using the Pythagorean identities we can find the sine of an acute angle.

What is angle ?

An angle is a measure of rotation about a point or a line. It is a geometric concept that describes the amount of rotation between two lines or planes. Angles are typically measured in degrees or radians.

What is acute angle ?

An acute angle is an angle that measures less than 90 degrees. It is an angle that is smaller than a right angle. Acute angles are commonly found in triangles and other geometric shapes. They are represented by the symbol "α" (alpha) in trigonometry.

What is Pythagorean identities?

The Pythagorean identities are a set of trigonometric identities that are based on the Pythagorean theorem. They relate the sine, cosine, and tangent of an angle to the ratios of the sides of a right triangle. The Pythagorean identities can be used to find the sine of an acute angle by relating it to the ratio of the opposite side to the hypotenuse of a right triangle.

Specifically, the identity [tex]sin^2(x) + cos^2(x) = 1[/tex] can be used to find the sine of an acute angle x by first finding the cosine of x and then subtracting it from 1.

The equation becomes [tex]sin(x) = \sqrt{1 - cos^2(x)}[/tex].

Multiplication: Decimal point moves right for every 10^n.

Division: Decimal point moves left for every 10^n.

When you multiply a number by a power of 10, the placement of the decimal point shifts to the right by the number of zeroes in the power of 10. For example, if you multiply 2.34 by 100 (102), the result would be 234.0, with the decimal point shifting two places to the right.

If the lines are parallel, then the pair of equations representing parallel lines have no solution.

Parallel lines are straight lines which, existing in the same plane and being produced indefinitely in both directions, do not meet one another in either direction. Another term involved is the "plane". We keep the Plane as an undefined term. The only thing is that we can represent it intuitively or explain it with the help of a physical model.

The degree of the polynomial of 7x ³ 5x 4x ³ 2x ² is 3.

The largest power of a component in a polynomial expression is the polynomial's degree.

Just to clarify your position, a polynomial is an expression with more than two algebraic terms, typically the sum (or difference) of various terms with various powers of the same or distinct variables (s). It is a monomial linear combination.

The polynomial can be divided into those with single value and those with many variables (multivariable polynomial).

As was previously said, the higher power of the polynomial expression is the degree of the polynomial with one variable.

The equation y = -2x + 5 is already in the standard slope intercept form.

The slope-intercept form is a way of expressing the equation of a straight line in algebraic terms. The equation of a line in slope-intercept form is typically written as:

y = mx + b

Where m represents the slope of the line and b represents the y-intercept, which is the point at which the line crosses the y-axis. The slope-intercept form is useful because it allows you to quickly identify the slope and y-intercept of a line, given its equation. The slope represents the rate of change of y with respect to x, and the y-intercept represents the initial value of y when x is equal to 0. By using slope-intercept form we can easily graph the line and also can find the equation of the line from the graph.

The value of input is -8 when the output is -10.

A function is a mathematical relation between a set of inputs (also called independent variables) and a set of outputs (also called dependent variables). It assigns a unique output to each input in its domain. Functions are often represented by mathematical expressions, graphs, or tables. In computer science, functions are used to organize and structure code by breaking it down into smaller, more manageable tasks.

The function describes that the value of function is  6 more than 2 times tha input

so f(x)  = 2x + 6

so this is required function according to the description.

given that output of the function is -10

so f(x) = -10

=> 2x+6 = -10

Answer: The equation of a line can be written in the slope-intercept form y = mx + b, where m is the slope of the line and b is the y-intercept.

To find the equation of a line that passes through the point (3, 2) and cuts off equal intercepts on the x and y axes, we can use the following steps:

First, we need to find the slope of the line using the point (3, 2) and the fact that the line cuts off equal intercepts on the x and y axes. Since the line cuts off equal intercepts on the x and y axes, it means that it is a line of symmetry, which means that the slope of the line is zero.

Now we can use the point-slope form of a linear equation which is y-y1 = m(x-x1) and substitute the point (3,2) and the slope (0)

The equation of the line will be y = b where b is the y-intercept.

So the equation of the line which passes through the point (3, 2) and cuts off equal intercepts on the axes is y = 2

The line is a horizontal line passing through the point (3,2) and it cuts the x-axis at y = 2.

In the given question of inequality, the greater than symbol makes the statement true, 14 > 5/6​.

A relationship between two expressions or values that is not equal to each other is known as inequality in mathematics. So inequality emerges from an imbalance.

"Less than or equal to," "less than," or "not equal to" are all ways to describe an inequality, which is a mathematical relationship between two expressions.

Both equations and inequalities are mathematical phrases created by connecting two expressions. The equal sign (=) in an equation denotes that the two expressions are regarded as equal. In contrast, an inequality indicates that the two phrases are not always equal by using the symbols >, <, or =.

Less than or equal to, larger than, less than, and more than or equal to are the four fundamental inequalities.

No, a polynomial is not always a binomial. A binomial is a polynomial of two terms, while a polynomial can have any number of terms.

Since polynomials can have more than two terms, they are not all binomials.

For instance

A polynomial but not a binomial is 2x2 + 3x + 4.

A polynomial and a binomial, 2x2 + 6

The assertion thus is false.

For some whole integer n, a polynomial is the sum of n monomials. As a result, polynomials are a general term for monomials, binomials, and trinomials.

You can have as many terms as you like in a polynomial. The exponents of all a monomial's variables are added to determine its degree.

Given that ∠1 and ∠2 form a linear pair.

m∠1 + m∠2 = 180°

Also, m∠1 is eighteen less than twice m∠2.

m∠1 = (2 × m∠2) - 18

(2 × m∠2) - 18 + m∠2 = 180°

3 × m∠2 - 18 = 180

3 × m∠2 = 198

m∠2 = 198 / 3
