The solution to the equation is x = 7.
What is the linear equation in one variable?
A linear equation in one variable is an equation of the form ax + b = 0, where a and b are constants and x is the variable. The general form of a linear equation in one variable is ax + b = 0, where a and b are constants and x is the variable. The graph of a linear equation in one variable is a straight line.
The first step in solving the equation 2x - 4 = 10 using algebra tiles would be to add 4 to both sides of the equation to get 2x = 14. The next step would be to divide both sides of the equation by 2 to get x = 7.
Hence, the solution to the equation is x = 7.

true/false. in the greek geocentric model, the retrograde motion of a planet occurs when: in the greek geocentric model, the retrograde motion of a planet occurs when: earth is about to pass the planet in its orbit around the sun. the planet actually goes backward in its orbit around earth. the planet is aligned with the moon in our sky.
According to the Greek geocentric paradigm, a planet moves retrogradely when it actually goes backward in its orbit around Earth. So the option b is correct.
The geocentric paradigm, also known as geocentrism, which is frequently and particularly shown by the Ptolemaic system, is an outdated explanation of the cosmos that places Earth at its center. The Sun, Moon, stars, and planets all orbit Earth according to the majority of geocentric models.
Since humans have been gazing up at the stars for thousands of years, our perception of what the Universe looks like has undergone a significant transformation.
In time, humanity also realized that the Earth was a sphere and developed logical justifications for how other heavenly bodies behaved. By classical antiquity, scientists had developed theories about how the planets moved and how all the celestial bodies interacted. This led to the development of the now-defunct Geocentric model of the cosmos, which described how the Sun, Moon, and firmament revolved around our earth.

A cosine and sine function can be expressed in terms of an imaginary exponential using Euler's formula: e^(iθ) = cos(θ) + i*sin(θ).
This formula can be derived by using the Taylor series for e^x, and replacing x with iθ.
A cosine and sine function can be expressed in terms of an imaginary exponential using Euler's formula: e^(iθ) = cos(θ) + i*sin(θ).
Conversely, an imaginary exponential can be expressed in terms of cosine and sine by solving for θ in the above equation. This can be done by taking the inverse cosine and inverse sine of both sides to get θ = cos^(-1)(e^(iθ)) = sin^(-1)(i*sin(θ)). Combining these equations gives θ = sin^(-1)(i*(e^(iθ) - cos(θ))).

State if the three numbers can be the measures of
the sides of a triangle.
4,7,8
Select the correct response:
O True
O False
True. The three numbers can be the measures of the sides of a triangle.
What is the triangle inequality theorem?
The triangle inequality theorem is a fundamental principle in Euclidean geometry that states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. This means that in any triangle, no side can be longer than the sum of the other two sides.
The three numbers 4, 7, and 8 can be the measures of the sides of a triangle. This is because of the triangle inequality theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In other words, for any triangle, the sum of two sides must always be greater than the third side.
For example, in this case,
4 + 7 = 11 > 8,
7 + 8 = 15 > 4,
4 + 8 = 12 > 7
Hence, 4, 7, and 8 can be the measures of the sides of a triangle, so the correct response would be "True".

Use the algebraic tests to check for symmetry with respect to both axes and the origin.
y = x^4 - x^2 + 3
Axis of Symmetry: This function is not symmetric with respect to the x-axis, y-axis, or the origin.
To check for symmetry with respect to both the x-axis and the y-axis, we need to check whether the function is even or odd. To do this, we can substitute -x for x in the equation and check if the equation remains the same.
y = x^4 - x^2 + 3
y = (-x)^4 - (-x)^2 + 3
y = x^4 - x^2 + 3
Since the equation remains the same, the function is neither even nor odd and therefore is not symmetric with respect to either the x-axis or the y-axis.
To check for symmetry with respect to the origin, we need to check if the equation is symmetric when x and y are both substituted with -x or -y.
y = x^4 - x^2 + 3
y = (-x)^4 - (-x)^2 + 3
y = x^4 - x^2 - 3

One-half the sum of two numbers is 12. One of the numbers is three more than two times the other number. What are the two numbers?
Answer:
The two numbers are 17 and 7
Step-by-step explanation:
Translate this word problem into a math equation
If we let x and y be the two unknown numbers
One-half the sum of two numbers is 12 ==>
sum of two numbers : x + yone-half the sum of two numbers : (1/2)(x + y)one-half the sum of two numbers is 12: (1/2)(x + y) =12
So one equation is 1/2(x + y) =12
Multiplying throughout by 2 gets rid of the denominator:
2 x 1/2 x (x + y) = 2 x 12
x + y = 24 (1)
One of the numbers is three more than two times the other number:
x = 2y + 3
or
x - 2y = 3 (2)
Equation (2) - Equation (1) =>
x + y - (x -2y) = 24 - 1
x + y - x + 2y = 21
3y = 21
y = 21/3
y = 7
With y = 7, substituting in equation 1 gives
x + y = 24
x + 7 = 24
x = 24-7
x = 17

What are Coterminal angles?Coterminal angles are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side.
Coterminal angles are two angles in the standard position where one angle is a multiple of 360 degrees larger or smaller than the other. That is, if angle A has a measure of M degrees, then angle B is co-terminal if it measures M +/- 360n, where n=0,1,2,3, ...
Starting from that position, 300° is drawn by moving around the circle to the left "counter-clockwise" and ending at the 300° measure.
The negative coterminal angle is the angle that would end in the same place if we went to the right instead of right on the circle. It is equal to the original 300° minus 360°
Coterminal angles Ac to angle A may be obtained by adding or subtracting k⋅360° or k × (2π)
Hence, Ac = A + k⋅360°, if A is given in degrees.
