Asystem of equations is shown. y = 3x - 2; . y = x^2. what are the solutions to the system of equations?

the solutions to the system of equations are x = 2 and x = 1

Step-by-step explanation:

The system of equations given equation is

y = 3x - 2 - - - - - - - - - - 1

y = x^2 - - - - - - - - - - - - 2

Substituting 1 into equation 2, it becomes

x^2 = 3x - 2

x^2 - 3x + 2 = 0

We would apply the method of factorization in solving the equation. We will get two numbers such that when added, the result would be - 3x and when multiplied, the result would be 2x^2. The numbers are - 2x and - x. It becomes

x^2 - 2x - x + 2 = 0

x(x - 2) - 1(x - 2) = 0

(x - 2)(x - 1) = 0

x - 2 = 0 or x - 1 = 0

x = 2 or x = 1

.

(1,1) and (2,4) are the solutions to the system of equations.

Step-by-step explanation:

The two equations are:

---------1

---------2

Putting value of y from equation 1 in equation 2 we get:

When x=1 :

When x=2

The solutions are (1,1) and (2,4).

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
