system of equation substitution method

2012-06-07T05:07:00.000-07:00

System of Equation

Free Math Education (Algebra Math) Students learn to solve systems of equations by substitution by first isolating a variable in one of the equations in the system, then substituting its value for the corresponding variable in the other equation. You can also learn to solve the equations by the method of their choice using the following rules:

if one of the variables cancels out when the equations are added together, then use addition, and if a variable is already isolated in one of the equations, use substitution method.

slope of a straight line

2012-04-25T06:45:00.002-07:00

Slope of a line

Process to find the slope of a line:

We can take any two point on a line.
Find the vertical change or change in y coordinate.
Find the horizontal change or change in x coordinate.
Find the ratio of these changes i.e. m = rise/run

Slope = change in coordinate y / change in x coordinate

We have basically 4 types of slopes. These are:

Zero Slope: In this case the line is parallel to the x axis, The value of x is change or increased, the value of y remains constant or unchanged.
Positive Slope: In this case as the values of x increase, the value of y is also increased and the slope of a line is positive.
Negative Slope: In this case as the values of x increase, the value of y is decreased and the slope of a line is negative.
No slope: In this case the line is parallel to the y axis, The value of y is change or increased, the value of x remains constant or unchanged.

Positive Negative Integers

2012-04-25T06:05:00.001-07:00

Positive and Negative Integers

"The Integers" is a part of real numbers.

The Integer is a whole number, i.e. if the number is greater than 0 (zero) called the Positve Integers and those numbers less than zero called the Negative Integers. Zero is neither positive nor negative.

For every Positive Integer, there's exist a Negative Integer whihc is equal distance from the origin (0).
Two integers that lie the same distance from the origin and located in opposite directions from the orign are called the opposites. For example, "positive 9" (+9) is the opposite of "negative 9." (-9).

Orthocenter of a Triangle ABC

How to Find the orthocenter of a Triangle

The orthocenter of a triangle is where all of the altitudes of a triangle meet each other.

The altitude is a perpendicular line segment from a vertex of a triangle to the opposite side (Vertex A to side BC).

To draw the orthocenter, first You draw the triangle on a coordinate plane and draw all three altitudes (one from each vertex of the triangle) and determine the point at which they all intersect. This intersection is a orthocenter of a Triangle ABC.

step by step solution substitution method

2012-03-08T05:14:00.000-08:00

Substitution Method

Calculate value of x and y: Equations are y-x = 3 and 2(x + y) = 14

Solution:
In substitution method, we have a given equation of two variables, x and y.
First, divide in second equation by 2 in both sides.
x + y = 4 …. (1)
y – x = 3 => y = x + 3 ….(2)
Now, put the value of y in equation 1 and solve the equation for x, i.e
x + (x + 3) = 4
x + x + 3 = 4
2x = 4 –3
which gives x = 1/2.

Now, substitute x = 1/2 in any one of the given equation and find the value of y
y = 1/2 + 3
y = 7/2
Answer is : x = 1/2, y = 7/2

Solve for X:
2/3 X + 1 = X/6 x 3

Answer:
In given equation, we find the value of X.

We see that, the denominator of the given equation is 6, so we just multiplied the whole equation by 6.
6 (2/3 X + 1) = 6(X/6 x 3)

Using the distributive law, we have
4X + 6 = 3X

Now taken out the common terms in single side
4X –3X = –6

which gives
X = –6
Answer is : x = –6

Q.
4x + 3y = 1 and x = 1 – y
Solution:
In substitution method, we have a given equation of two variables, x and y.
First you put the value of x in other given equation 4x = 2x + 3y and calculate the value of y.
Steps are:
x = 1 –y
Plug ‘x’ in first equation.
4(1 –y) + 3y = 1
Solve this equation for y
4 –4y + 3y = 1
4 –y = 1
y = 3
Substitute y = 1 in any one of the given equation and find the value of other variable
x = 1 –y
x = 1 –3 = –2
Answer is : x = –2, y = 3

linear programming problem standard form

2012-02-08T06:19:00.000-08:00

Linear programming problem standard form

For developing a general method of solution of a linear programming problem, we used the standard form. The basics of standard form is

1. Non Negativity Constraints i.e. all the constraints are transformed into equations using the addition and substitution of new non negative constraints and change the equation into standard form. These new varaibles are called as slack or surplus variables and are added if <= sign in constraints and subtract if >= in the constraints.

correlation and regression formula

2011-12-02T03:33:00.001-08:00

Correlation and Regression

Correlation identify the degree of relationship between the two variables and Regression is used to study the nature of relationship between these variables.

In Case of bivariate population, we calculate the correlation coefficient by cross tabulation method, Charlie Spearman's coefficient and Karl Pearson Coefficient.

Cross tabulation is useful when given data are in nominal form. Under it we can classify each variable into two or more categories and then cross classify the variables in these sub categories.
1. Symmetrical
2. Reciprocal
3. Asymmetrical

In Symmetrical relationship is one in which the two variables are vary together, i.e. if one is increase or decrease other variable is also increase of decrease.

In case of Reciprocal relationship, when the two variables are mutually influence or reinforce to each other.

Asymmetrical relationship is exist if one variable (independent variable) is responsible for other variable (dependent variable).

Charlie Spearman's Rank Correlation Coefficient :

Karl Pearson Correlation Coefficient:

Steps of Research Process - Definition Literature Free Tutoring

The scientific method of research basics steps.

Defining a problem:

To start a research, we first of all need to discover the exact problem and which required the solution. The best way to find out or identity the problem area or problem is clearly identified and formulated.

Review of the Literature:

This literature survey involves a review of some published and unpublished work from the available secondary data sources or available data relevant to our study.

Free Home work help for algebra, geometry online tutorials

Formulation or Developing Working Hypothesis:

The hypothesis is the main point around which the future research efforts will be directed. All the data collected, the tools of analysis are influenced by the hypothesis. We use the null hypotheses (H₀) and alternative hypothesis (H_a) and find out the relevant relations between the different variables

Developing a Research Design:

Research designs outline the conditions for collection and analysis of data, for this we can find the information using sampling design techniques, data collection design and instrument design.

Collection of Data:

Using these (Convenience Sampling, Purposive Sampling, Judgment Sampling, random and cluster sampling, systematic sampling and many more) techniques to find the data collections.

Analysis of Data:

Now we analysis the data in details and follow the procedure - Coding, Editing, Tabulation and Statistical analysis presentation which needs to help to prepare the final report in research.

Drawing Conclusions:

All the tested hypotheses data interpretation is done with the results on the basic of all the theories

Reporting the Results:

In this section, results launched publically of the research so that the findings can be put to some use in further research. It contains the preliminary section (contains title of the report, table content preface etc), the main text section (contain the main problem area, objective, and research methodology) and the end section (queries, glossary items and supported materials.

Research Design

2011-11-26T20:50:00.001-08:00

The problem that follows the task of defining a research problem is the preparation of the design of the research project is called as a research design.

A research design is the arrangement of all the conditions of the collection & analysis and processed data in a manner that results the all the collection of data in research purpose with an economy in a procedure.

Mostly the final decision happens with respect of:

What is study about?
Why is study being made?
Where will the study be carried out?
What type of data will require?
Where can the required data be found?
What period of time will the study include.
How will the data be analysed.
Preparation of a report in final layout.

In briefly, research design must at least contains a clear Statement of the Research Problem, Procedures and Techniques to be used for gathering an information, the population to be studied and methods to be used to processing and analyzing the data in research hypothesis.
