A linear equation - y = 5x -7 is a slant line with intercepts for linear equations. A vertical line is x = 2. A line that runs through the origin is y = 3/4x.
A slant line with intercepts is y = 1/2x + 3. A horizontal line is y = 9. The line x = -1 runs vertically.
A linear equation is what?A direct condition is one that has a level of 1 as its most extreme worth. As a result, there is no variable in a linear equation with an exponent greater than 1. The graph of a linear equation will always be straight.
y = 5x -7 is the first line equation.This line is not horizontal or vertical when the equation is graphed; rather, it is slant.
Additionally, this line does not traverse the origin. As a result, this equation has intercepts and slant lines.
x = 2 is the second line equation.Since there is no y-intercept in this equation, it will be a vertical line that runs parallel to the y-axis.
Additionally, this line does not traverse the origin. As a result, this equation has a line that runs vertically.
y = 3/4x is the third equation for the line.This line is not horizontal or vertical when the equation is graphed; rather, it is slant.
Additionally, this line actually traverses the origin. As a result, the origin of this equation is traversed by slant lines.
y = 1/2x + 3 is the fourth equation for a line.This line is not horizontal or vertical when the equation is graphed; rather, it is slant.
Additionally, this line does not traverse the origin. This equation is therefore a slant line with intercepts.
y = 9 is the fifth line equation.Since there is no x-intercept in this equation, it will be a horizontal line that runs parallel to the x-axis.
Additionally, this line does not traverse the origin. As a result, there is a horizontal line in this equation.
x = -1 is the sixth line equation.Since there is no y-intercept in this equation, it will be a vertical line that runs parallel to the y-axis.
Additionally, this line does not traverse the origin. As a result, this equation has a line that runs vertically.

What are the 3 types of investors?
The three types of investors in a business are, active investors, pre-investors and passive investors.
Pre-investors:
A person who is simply not involved in any kind of investments, are
called as pre-investors. A pre-investor's financial world is primarily
based upon consumption by giving a little preference to savings or
investments.
Passive investors:It is a starting point of an individual's entering into the investment
world for an individual. When an individual graduates, and learn and
gain knowledge about investments, he sub-divides his income into
investments to expand his income further.
Active investors:Active investors are basically built upon the foundation of the

i am thinking of a fraction. The sum of the numerator and denominator is 19. When I add
8 to the denominator, the fraction becomes 1/2 What is the fraction I am thinking of?
Answer:
\(\frac{9}{10}\)
Step-by-step explanation:
Let the fraction be \(\frac{x}{y}\).
That would mean:
(1) x+y = 19
&
(2) y+8 = 2x or 2x = y+8
In order to use substitution, we multiply equation by 2:
(3) 2x+2y = 38
Then we substitute equation (2) into (3):
y+8 + 2y = 38
3y + 8 = 38
3y = 30
y = 10
Substitute this into equation (1)
x + 10 = 19
x = 9
Therefore the fraction would be:
\(\frac{9}{10}\)
Answer:
9/10
Step-by-step explanation:
let the fraction be x/y.
x+y=19
x/y+8=1/2
solve simultaneously
y=2x-8
y=19-x
2x-8=19-x
3x=27
x=9
y=10
To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this?
Henry could only see one line since both lines had the same slope, which means that the graphs of both equations will be identical and hence overlap.
Identify the linear equation?Linear equations in a system 3x + 2y = 4, and 9x + 6y = 12
We must demonstrate why Henry could only make out one line when he plotted the equations 3x-2y=4 and 9x-6y=12 on a graph.
Take the provided linear equation system into consideration.
3x - 2y = 4 ................(1)
9x - 6y = 12 ..................(2)
Due to the fact that equation (2) is a multiple of equation (1), 3 (3x - 2y = 4) = 9x - 6y = 12
The slopes of the provided equations are also same.

In △△KLM, MK (lines over MK)≅ LM.m∠L=43∘ . Find M.m∠M.
Answer:
Based on the definition of an isosceles triangle, the measure of angle L is: 43°
An isosceles triangle has two side lengths that are equal in size, and also the angles opposite the equal sides are congruent.
Given that KL ≅ MK in △KLM, it means △KLM is an isosceles triangle.
If m∠M = 43°, therefore, m∠M = m∠L (equal angles directly opposite KL and MK).
This implies that: m∠M = 43°
In summary, based on the definition of an isosceles triangle, the measure of angle M is: 43°

A farmer is constructing a rectangular pen with one additional fence across its width. Find the maximum area that can be enclosed with 360 yards of fencing
The maximum area of the pen is the highest area the pen can have
The maximum area is 16200 square yards
Let the dimension be x and y.
So, the perimeter is given as:
\(\mathbf{P = 360}\)
Because it has one additional fence, the perimeter is calculated as:
\(\mathbf{2x + y = 360}\)
Make y the subject
\(\mathbf{y = 360 - 2x}\)
The area is calculated as:
\(\mathbf{A = xy}\)
Substitute \(\mathbf{y = 360 - 2x}\)
\(\mathbf{A = x(360 -2x)}\)
Expand
\(\mathbf{A = 360x -2x^2}\)
Differentiate
\(\mathbf{A' = 360 -4x}\)
Set to 0
\(\mathbf{360 -4x = 0}\)
Rewrite as:
\(\mathbf{4x = 360}\)
Divide both sides by 4
\(\mathbf{x = 90}\)
Substitute 90 for x in \(\mathbf{A = 360x -2x^2}\)
\(\mathbf{A = 360 \times 90 - 2 \times 90^2}\)
\(\mathbf{A = 16200}\)
Hence, the maximum area is 16200 square yards

Find the difference between points M(6, 16) and Z(-1, 14) to the nearest tenth.
The distance between points M(6, 16) and Z(-1, 14) is approximately 7.1 units.
We can use the distance formula to find the distance between two points in a coordinate plane. The distance formula is:
d = √((x2 - x1)² + (y2 - y1)²)
where (x1, y1) and (x2, y2) are the coordinates of the two points. Substituting the coordinates of M(6, 16) and Z(-1, 14), we get:
d = √((-1 - 6)² + (14 - 16)²) = √(49 + 4) = √53 ≈ 7.1

Option - B : Decision support system is a flexible tool for data analysis, since its reports do not have a fixed format.
Decision support systems, a subset of business intelligence, are created to help organisations make sensible business decisions based on vast volumes of analysed data. Huge volumes of data are analysed using an interactive information system called a decision support system (DSS) to aid in the direction of business choices. A DSS aids management, operations, and planning levels of an organisation in making better decisions by assessing the importance of uncertainties and the tradeoffs involved in selecting one option over another. A DSS uses a variety of raw data, papers, personal knowledge, and/or business models to aid users in making decisions. A DSS may make use of relational data sources, cubes, data warehouses, electronic health records (EHRs), income projections, sales projections, and other sources.

En un mapa tienes que ir de la escuela a el mercado y del mercado a la biblioteca pero ¿Cómo se mide la distancia que hay entre cada uno de esos lugares si sale 1:10000 centímetros?
Answer:
La escala es 1 : 10000 centimetros
Eso significa que por cada centimetro que una persona mide en el mapa, en la vida real la distancia es 100 metros.
Por ejemplo, si usamos una regla para medir la distancia en el mapa y medimos que entre la escuela y el mercado hay una distancia de 7 centimetros (siguiendo las calles, no en linea recta), entonces la distancia a caminar para ir de la escuela al mercado es de 700 metros. Debemos ser cuidadosos y medir la distancia siguiendo las calles, ya que si medimos en linea recta la distancia puede ser menor, pero los humanos no volamos.

The value of T(v), express v as linear combination in the basis B and the matrix representation of T obtain is T(v) = [4, -4].
To find T(v), we need to express v as a linear combination of the basis vectors of R^3 with respect to B:
v = (-1)[0] + (-1)[0] + (1)[1]
This means that the coordinate vector of v with respect to B is [-1, -1, 1].
To find the matrix representation of T with respect to the standard bases of R^3 and R^2, we can apply T to each of the basis vectors:
T([1, 0, 0]) = [1, 3]
T([0, 1, 0]) = [-1, 1]
T([0, 0, 1]) = [2, -2]
We can arrange the results in a matrix:
[1 -1 2]
[3 1 -2]
The matrix [1 -1 2; 3 1 -2] represents T with respect to the standard bases of R^3 and R^2.
To find T(v), we can multiply the matrix representation of T with the coordinate vector of v with respect to B:

The function f : Z x Z → Z x Z defined by the formula f(m,n) = (5m+4n, 4m+3n) is bijective. Find its inverse.
The function f : Z x Z → Z x Z defined by \(f(m,n) = (5m+4n, 4m+3n)\) is bijective, with its inverse given by \(f^{-1}(m,n) = (-3m + 4n, 4m - 5n)\). This means that for every pair of integers (m,n), the function f maps them uniquely to another pair of integers, and the inverse function \(f^{-1}\) maps the resulting pair back to the original pair.
The inverse of the function f(m,n) = (5m+4n, 4m+3n) is \(f^{-1}(m,n) = (-3m + 4n, 4m - 5n)\).
To show that the function f is bijective, we need to prove both injectivity (one-to-one) and surjectivity (onto).
Injectivity:
Assume f(m1, n1) = f(m2, n2), where (m1, n1) and (m2, n2) are distinct elements of Z x Z.
Then, (5m1 + 4n1, 4m1 + 3n1) = (5m2 + 4n2, 4m2 + 3n2).
This implies 5m1 + 4n1 = 5m2 + 4n2 and 4m1 + 3n1 = 4m2 + 3n2.
By solving these equations, we find m1 = m2 and n1 = n2, proving injectivity.
Surjectivity:
Let (a, b) be any element of Z x Z. We need to find (m, n) such that f(m, n) = (a, b).
By solving the equations 5m + 4n = a and 4m + 3n = b, we find m = -3a + 4b and n = 4a - 5b.
Thus, f(-3a + 4b, 4a - 5b) = (5(-3a + 4b) + 4(4a - 5b), 4(-3a + 4b) + 3(4a - 5b)) = (a, b), proving surjectivity.
Since the function f is both injective and surjective, it is bijective. The inverse function \(f^{-1}(m, n) = (-3m + 4n, 4m - 5n)\) is obtained by interchanging the roles of m and n in the original function f.
