Question

Answer 1

I'm not sure what an open sentence is. This sounds like an english question. Could you try posting this in the english section. Thanks.
And sorry for that spammer.

Answer 2

No this is math.

Answer 3

What is an open sentence?

Answer 4

lol and sorry i didn't know it was
just never heard of it

Answer 5

Examples of open sentences include:
3x − 9 = 21, whose only solution for x is 10;
4x + 3 > 9, whose solutions for x are all numbers greater than 3/2;
x + y = 0, whose solutions for x and y are all pairs of numbers that are additive inverses;
3x + 9 = 3(x + 3), whose solutions for x are all numbers.
3x + 9 = 3(x + 4), which has no solution.
There are some examples I found of open sentences.

Answer 6

let me see if i can look at the pattern and determine a real world example

Answer 7

Oh no its okay now! I got the answer haha.

Answer 8

We need to put some money into our bank account such that are account is no longer negative. We could put in 25 dollars or more in order for our balance to be 0 or positive.

Answer 9

Hey vanz thanks for giving me vocabulary.

Answer 10

more vocabulary*

Answer 11

Do you have anything for equations of a line? and no problem thanks for the help. :)

Answer 12

y=mx+b anything that can be written in this form is a line

Answer 13

or even x=constant or y=constant

Answer 14

these are all lines and if an equation can not be written in any of these forms then it is not linear
is that what you were looking for?

Answer 15

I am looking for real world examples like when would I ever use this

Answer 16

oh

Answer 17

hmmm.... I know you can use it some jobs that involve technology.

Answer 18

I cannot think of an example off the top of my head.

Answer 19

let me see if i can find someone who can think of an example

Answer 20

okay Thank you! I'll wait.

Answer 21

line goes on forever
what can i say goes on forever?

Answer 22

i guess we could say that we can make two linear equations for two train tracks whose tracks are almost linear and find their approximate intersection

Answer 23

That works! :D

Answer 24

thats the best i can think of lol

Answer 25

do you have any examples for system of linear? :D

Answer 26

that was it actually

Answer 27

that was a system of linear equations above

Answer 28

like i can use it as an equation of a line example AND linear equations?

Answer 29

i don't see why not
