Question

when you are solving for a variable in an inequality do you flip the inequality sign if you divide?

Answer 1

i like flipping in all circumstances
but no only if the number is negativef

Answer 2

so when I divide by P in this equation I dont flip the sign?

Answer 3

You reverse the inequality sign whenever

i). you multiply or divide both sides of the inequation by a negative,
ii). read the inequation backwards, or
iii). take the reciprocal of both sides as long as both sides are positive or both sides are negative.

Answer 4

god i want sooo bad to know where this question comes from

please please please i beg you to tell me

Answer 5

flvs why?

Answer 6

how did i guess?

Answer 7

you cannot solve this problem for n
it cannot be done
and you asked a very good question, when do you flip the inequality

Answer 8

the answer is when you multiply or divide by a negative number
but the idiot who wrote this question does not understand that a variable can either be positive or negative

Answer 9

The Algebra teachers at my school are terrible so I take it online. I've come across a number of questions like this, put I've found even more in the school text book.

Answer 10

please can you give me the id number of this question ? it is shameful

Answer 11

I am not solving for n. I am finding how I would solve for n if there where numbers in place of the variables. Would you like to see the whole question?

Answer 12

i once wrote to FLVS asking why their questions sucked so bad
(not in so many words) they asked for id numbers if i had it i could give an example

Answer 13

i would love to

Answer 14

what do you mean by "id numbers"?

Answer 15

the questions come with id numbers, maybe you do not see them
the image will be good enough
they are criminals

Answer 16

about the original question, I wouldn't flip the sign?

Answer 17

here is the thing
YOU DON'T KNOW!! no one knows, because you don't know if the variables are positive or not
you can't know
but we can still pretend

Answer 18

the variable is negative

Answer 19

no it isn't

Answer 20

it is a variable

Answer 21

it is look at the picture. it says -np-4

Answer 22

god help me
it is not your fault

Answer 23

If you were not given answer choices, would you be able to determine whether p or n were negative or positive?

Answer 24

lets go ahead and solve

Answer 25

since it says -np I should think so

Answer 26

NNOOOOO that is the whole point!

Answer 27

ok. I thought the answer would be either a or c

Answer 28

you are being lead to believe that \(-p\) is negative because it has a minus sign

Answer 29

i understand this, but you should be smarter than the florid school board
if for example \(p=-4\) then \(-p=4\)

Answer 30

lets solve then i will go take a valium

Answer 31

ok.

Answer 32

\[-np-4\leq 2(c-3)\\
-np-4\leq 2c-6\\\
-np\leq 2c-2\]

Answer 33

ok then you divide by p

Answer 34

now they want you do divide by \(-p\) and change the inequality because they are so uneducated as to think \(-p\) is negative and get
\[n\geq -\frac{2c-2}{p}\]

Answer 35

ok so th3 answer is c?

Answer 36

sorry, the, old habits

Answer 37

that is what they want you to think, yes

Answer 38

ok thanks

Answer 39

write to them and tell them that they don't understand what a variable is

Answer 40

that they have no business teaching math

Answer 41

i know i will

Answer 42

it's how they've taught it to me...

Answer 43

thanks for the screenshot btw

Answer 44

no problem.

Answer 45

they should be prosecuted

Answer 46

feel free. XD
