The equation which gives infinite solutions, x-10+x = 8+2x-18.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
For the infinite solution the both side of equation must contain equal quantity.
For example,
x-10+x = 8+2x-18
now, solving for x
x-10+x = 8+2x-18
2x-10 = 2x-10
-2x = -2x
-10 = -10
As, both sides are equal which shows the system of equation.

Find the hypotenuse use simplest radical form if necessary
As a result, according to Pythagoras' Theorem, the third side, or hypotenuse, has a value of 8 units, whereas the other two sides are 6 and 7.
what is Pythagoras' Theorem ?The Pythagorean Theorem, often known as the Pythagorean Theorem, is the fundamental Euclidean geometry relationship between the three sides of a right triangle. The area of a square with the hypotenuse side equals the sum of the areas of squares with the other two sides, according to this rule. The Pythagorean Theorem says that the square that spans a right triangle's hypotenuse opposite the right angle equals the sum of the squares that span its sides. It is sometimes written as the generic algebraic notation a2 + b2 = c2.
given
x2 = a2 + b2
x2 = 6*6 + 28
x2 = 36 + 28

A reflective pronoun is a pronoun formed with -self or -selves that refers to the subject. Hence, option B is correct.
What is reflective pronoun?When a pronoun is used to refer to the same noun as both the subject and the object of a verb, it is known as a reflexive pronoun. The pronouns that in English finish in "self" or "selves" are things like "himself," "myself," "ourselves," etc.
Words like myself, you, him, her, it, ourselves, ourselves, and yourselves are examples of reflexive pronouns. They make a reference to someone or something. When the subject and the object of a verb are the same, reflexive pronouns are frequently used. I cut myself yesterday night while preparing dinner.

It costs $4 for 2 visits, $8 for 4 visits, $10 for 5 visits, and $16 for 8 visits.
Fill in the table to find how much it costs for 2, 4, 5, and 8 visits ?2 visits: c = 2v = 2(2) = $4,
4 visits: c = 2v = 2(4) = $8,
5 visits: c = 2v = 2(5) = $10,
8 visits: c = 2v = 2(8) = $16.
Therefore, it costs $4 for 2 visits, $8 for 4 visits, $10 for 5 visits, and $16 for 8 visits.2 visits: c = $30, cost per visit = $15
4 visits: c = $60, cost per visit = $15
5 visits: c = $75, cost per visit = $15
8 visits: c = $120, cost per visit = $15
As seen in the table above, the cost to get your hair done for 2, 4, 5, and 8 visits is $30, $60, $75, and $120 respectively.This means that no matter how many visits you make, the cost per visit stays the same at $15.This is a great deal for customers as they can enjoy the same services for a fixed price.This theory is called the "linear cost model." It is based on the idea that the cost of a product or service is proportional to the number of units that are purchased.In this case, the cost per visit is constant, and the total cost increases in a linear fashion as the number of visits increases.This model is useful for determining the cost of a service or product for a variety of customers, as the cost per unit is known.To learn more about linear cost model refer to:

The substitution reactions are classified into three groups,
nucleophilic substitution electrophilic substitution homolytic substitution.In the nucleophilic reactions the atom is said to be rich in electron , whereas, in the electrophilic reaction, the atom is known to be an electron-deficient species.

Create two complex numbers a+bi, where b≠0, such that the product of your numbers is 821
The product of two complex numbers, with a result of 821, is given as follows:
(26 + 12.04i)(26 - 12.04i) = 821.
What are complex numbers?Complex numbers are numbers that are composed by a real part and by an imaginary part, and have the notation given as follows:
z = a + bi.
In which:
a is the real part.b is the imaginary part.The most important complex numbers relation is given as follows:
i² = -1.
Meaning that the easiest way to obtain the desired product is multiplying complex-conjugate numbers, as follows:
(a + bi)(a - bi).
Applying the subtraction of perfect squares, we have that:
(a + bi)(a - bi) = a² - (bi)²
(a + bi)(a - bi) = a² - b²i²
(a + bi)(a - bi) = a² + b² (as i² = -1).
Then, attributing a = 26, the value of b is obtained as follows:
a² + b² = 821
26² + b² = 821
[tex]b = \sqrt{821 - 26^2}[/tex]
b = 12.04.

What are the 5 coordinate systems?
The 5 coordinate systems are Cartesian Coordinate System, Polar Coordinate System, Cylindrical Coordinate System, Spherical Coordinate System, Elliptic Coordinate System.
1. Cartesian Coordinate System: This system uses two perpendicular axes (X and Y) to determine the location of a point. The point's coordinates are the distances from the origin point (0, 0). The axes divide the plane into four quadrants and the coordinates can be positive or negative. The axes are also referred to as the x-axis and y-axis.
2. Polar Coordinate System: This system uses an angle and a distance from a fixed origin point to specify a point. The angle is measured in radians and the distance is measured from the origin. The coordinates of the point are usually written as (r, θ).
3. Cylindrical Coordinate System: This system combines the two-dimensional polar system and the one-dimensional Cartesian system. It uses three coordinates, (r, θ, z) to determine a point's location in three-dimensional space. The r coordinate is the distance from the origin, θ is the angle measured from the z-axis, and z is the height.
4. Spherical Coordinate System: This system uses three coordinates, (r, θ, φ), to determine a point's location in three-dimensional space. The r coordinate is the distance from the origin, θ is the angle measured from the z-axis, and φ is the angle measured from the x-axis.
5. Elliptic Coordinate System: This system uses two coordinates, (a, b), to specify a point on an ellipse. The a coordinate is the distance from one of the ellipse's foci, and the b coordinate is the distance from the other. This system is useful for describing orbits, such as those of planets.

When an image is enlarged using a scale factor between 1 and 1, the image does not change in size.
A scale factor of 1 means that the image is not being enlarged or reduced in size; it is remaining the same size. Therefore, the image will appear the same as it did before the enlargement.
A scale factor of less than 1 means that the image is being reduced in size, and a scale factor greater than 1 means that the image is being enlarged in size. But when it comes to scale factor between 1 and 1, the image will not change in size, it will appear the same as it was before.
