Pam and Jim are working on math homework. Their teacher gave them the following problem.
Use an inverse operation to help solve the equation xminus26equals28.
As the first step in solving, Pam writes xminus26plus26equals28plus26. Jim writes xminus26minus26equals28minus26. Who is incorrect, and why?
Choose the correct answer below.
A.
Jim is incorrect because he added 26 to each side instead of subtracting.
B.
Jim is incorrect because he subtracted 26 from each side instead of adding.
C.
Pam is incorrect because she subtracted 26 from each side instead of adding.
D.
Pam is incorrect because she added 26 to each side instead of subtracting.

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.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
