Choose an equation that when paired with the equation below, will create a system of equations with infinitely many solutions, one solution, or no solutions.

Infinitely many solutions:

One solution:

No solution:

Step-by-step explanation:

 Solve for y from each equation to obtain the equation of the line in slope-intercept form:

m: slope

b: y-intercept

EQUATION ON THE TOP:

Equation 1:

The equation on top and the equation equation 1 has different slopes and different y-intercept, therefore the system will have one solution.

Equation 2:

The equation on top and the equation equation 2 are the same, therefore, the system will have infinitely many solutions.

Equation 3:

The slopes are equal, then both lines will be parallels, therefpre  the system will have no solution.

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.
