Y=|x−3|+|x+2|−|x−5|, if 3
denis-greek [22]

Answer:

Step-by-step explanation:

I take it you want x = 3

y = abs(3 - 3) + abs(3 + 2) - abs(3 - 5)

y = 0 + 5 - abs(-2)

y = 0 + 5 - (2)

y = 0 + 5 - 2

y = 3

If you meant something else please leave a note.

Now all you do is redo the problem for 5

y = abs(5 - 3) + abs(5 + 2) - abs(5 - 5)

y = abs(2) + abs(7) - abs(0)

y = 2 + 7 - 0

y = 9

Now set up your inequality

3 < y < 9

Describe at least two advantages and two disadvantages of free-response questionnaires.​
Ksivusya [100]

Answer:

Advantages:

- It is easier for people to choose an option rather than to write an essay. The questionnaire reflects what the person is thinking and what the person's point of view is, which as a result makes it easier to analyze and conclude results

- A wide range of questions can be asked within one questionnaire, which makes it an effective way to conduct a survey/test

Disadvantages:

- A person has to read carefully in order to answer each question and sometimes there is lack of concentration by the person filling in the questionnaire

- It is slightly difficult to write an effective questionnaire, that would able to test a vast knowledge/  conduct a survey so that an effective  analysis can be done
