Orthocenter: Solve system of 3 eqs. using 3 altitudes' equation & vertices' coordinates.

What is coordinate ?

Coordinate is a value or set of values that identify the position of a point in a certain space. Represented by ordered pair or triple of numbers (x,y) or (x,y,z) respectively.

The orthocenter of a triangle is the point where the three altitudes of the triangle intersect. To find the orthocenter of a triangle with coordinates, you can use the following steps:

1) Find the equation of the three altitudes of the triangle. To do this, you will need the coordinates of the three vertices of the triangle, as well as the slope of the line perpendicular to the side opposite each vertex.

2) Once you have the equations of the three altitudes, you can use them to find the coordinates of the orthocenter. To do this, you will need to solve a system of three equations with three variables (the x and y coordinates of the orthocenter, and the y-intercept of the altitude).

3) Once you have the coordinates of the orthocenter, you can use them to check your work by verifying that the point is indeed on each of the three altitudes.

There are three types of systems of linear equations in two variables: Consistent System,Inconsistent System,Dependent System.

A linear system is a mathematical model of a system of linear equations, in which the variables and constants have a linear relationship. This type of system is widely used in engineering, physics, economics, and other areas of study. Linear systems are often used to find solutions to problems in areas such as optimization or forecasting. They are also used in many machine learning algorithms. Linear systems are characterized by their linearity and they are usually solved using linear algebra techniques.

1. Consistent System: A consistent system of linear equations in two variables has at least one solution. This means that there is at least one set of values for the two variables that will make all equations true.

2. Inconsistent System: An inconsistent system of linear equations in two variables has no solution. This means that there is no set of values for the two variables that will make all equations true.

3. Dependent System: A dependent system of linear equations in two variables has an infinite number of solutions. This means that there is more than one set of values for the two variables that will make all equations true.

Answer:

Step-by-step explanation:

given 2 sides of a triangle then the third side SU is in the interval

difference of 2 known sides < SU < sum of 2 known sides , that is

52 - 39 < SU < 52 + 39

13 < SU < 91

Answer: it is table "a"

explanation:

as the equation is y= 2x + 5 you should substitute each of the x values from -2 to 4 in order to get the y value which will help you decide which table should be used by Cindy to graph the equation.

now, this is how you should substitute the values into the equation and simplify it so that you get the "y" value.

the first x value given is -2 therefore:

you put -2 in the equation instead of putting x, this will allow you to find the y value which you can compare with the choices given.

y= 2x+5 (this is the equation)

y= 2(-2)+5 (here I have replaced the x with -2)

y= -4+5 (you should multiply 2 and -2)

y= 1 (therefore the answer is 1)

you should further continue this way and get the y values which will help you decide which is the correct table to be used. Now you already know that table "a" is the answer.

Answer:

The answer is table A

Step-by-step explanation:

Given:

Answer:

Give more points

Step-by-step explanation:

Nico, Raj and Sandra are correct.

And the explanation is given.

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

An equation,

2/5(5 +x) = 8.

Nico, Aditi, Erick, Raj, and Sandra are solving the equation.

Approach 1:

Multiply by 5/2.

(5/2)(2/5)(5 +x) = 8(5/2)

5 + x = 20

x = 15.

Approach 2:

Multiply by 1/2 both sides

(1/2)(2/5)(5 +x) = 8(1/2)

5 + x = 4(5)

x = 15.

Approach 3:

Simplifying,

2 + 2/5x = 8

2x/5 = 6

x = 30/2

x = 15.

Therefore, Nico, Raj and Sandra are correct.

The ratio of the central angle measure to the circumference of a circle is called the "arc measure" and it is given by the formula:

arc measure = central angle measure / circumference

For a given central angle measure in degrees, the formula will be:

arc measure = (central angle measure in degrees) / 360

It's worth noting that this ratio is equal to the fraction of the circumference that the arc of the central angle measures.

For example, if the central angle measure is 90 degrees, the arc measure will be 90/360 = 1/4, meaning that the arc that is formed by the central angle measure is 1/4 of the circle's circumference.

It's also important to note that this ratio is also equal to the fraction of the total area of the circle that the sector formed by the central angle measures.

It's also worth noting that this ratio is always less than 1, since the central angle can't be greater than 360 degrees.

Therefore, The ratio of the central angle measure to the circumference of a circle is called the "arc measure" and it is given by the formula: arc measure = central angle measure / circumference

The rate of change of a horizontal line is zero, this is because it does not rise vertically (i.e. y1 − y2 = 0).

A rate of change of a horizontal line is the same as its slope, which is the change in y over the change in x, or rise over run.

For the horizontal line that is shown in the graph below, the rate of change for this line is 0, and this can be confirmed by utilizing the slope calculation method.

This makes sense because the change in y of the line is zero, which means it it does not rise vertically (i.e. y1 − y2 = 0).

Answer:

y = 5/2 x - 13

Step-by-step explanation:

A line perpendicular to y=-2/5x-1 has a slope equal to the negative reciprocal of -2/5. The slope of the line passing through (2,-8) can be calculated as follows:

m = -(-5/2) = 5/2

The equation of the line in point-slope form is:

y - (-8) = (5/2)(x - 2)

Expanding the equation gives:

y + 8 = 5/2 x - 5

Solving for y:

y = 5/2 x - 5 - 8

y = 5/2 x - 13

The equation of the line is:

y = 5/2 x - 13

The slopes for the given pairs are:

If a line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is given by:

a = (y₂ - y₁)/(x₂ - x₁)

Using the first pair of points (9, 10) and (7, 2) the slope is:

s = (2 - 10)/(9 - 7)

s = -8/2 = -4

For the second pair:
