Question

see attached !

Answer 1

false?

Answer 2

since it begins from number 5
we easily can check it out

\[\LARGE a+4<0\]

\[\LARGE 5+4=9 \quad \quad \]

so it's equal to nine not lower ... so it's false !

Answer 3

sorry ... \[\LARGE a+4<9\]

Answer 4

thats what i thought, thank you for the help !

Answer 5

Glad to help... You're welcome

Answer 6

No, that's true

Answer 7

a<5

Answer 8

a=/=5, which is why there is an open circle.

Answer 9

true a<5

Answer 10

@Kreshnik ?

Answer 11

@inkyvoyd you have a+4<9

not a<9 there's no question about "a"

only to prove if a+4<9

so the greatest value of a is 5 j

and we have

4+5=9

what's confusing you?

Answer 12

The solution for a+4<9 can be shown to be equivalent to a<5.
The picture for the solution on a number line is an open circle and the line on the left highlighted. This fits the exact problem.

Answer 13

@karakuhnn your question is not fully complete !... I THINK that line in red represents value of "a" if it represents the value of a+5 then it's true !!

Answer 14

@inkyvoyd do you see anywhere if it asks if a<9 ???

Answer 15

"the solution to the equation is shown on the line below"

Answer 16

solution of equation = a<5

Answer 17

oh well the answer is true. i got it right on my test.

Answer 18

solution of the equation graphed is shown on the graph below.

Answer 19

See, you gave kreshnik a medal for a false ansdwer xD

Answer 20

I still don't understand.... "dumb test !"

Answer 21

@inkyvoyd take it back I don't need medals don't worry ! ....

and my answer was RIGHT because I thought different !

why you're so jealous

Answer 22

no, you haven't justified your answer very well.

Answer 23

The solution of the equation is explictedly assumed to be the highlighted line segment.

Answer 24

the solution to a+4<9 is a<5, and when drawn on a number line, is represented standardly in almost all nations as an open circle on the 5 (to represent the exclusion of the number 5) and all numbers less than 5 highlighted. This is represented by highlighting all of the left side of the number line.

Answer 25

The red line is explicitly mentioned as the solution to the equation, not the value of a. And, the value of a is the solution to the equation. By solving the equation, we merely write it in a simpler form.

Answer 26

@Kreshnik , please read the problem attached in the screenshot a second time, this time more closely. I believe that you will see what I'm trying to say.

Answer 27

@inkyvoyd don't worry , I have it on tab ... but even if that is a+4<9

a<9-4

a<5

right?

then why it doesn't start from number 4 but from number 5?

Answer 28

Because that line is talking about a

Answer 29

4.1,4.3, even 4.99 are solutions.

Answer 30

4.9999999999999999999999999 is also a solution

Answer 31

it starts at 5, but note that it is an "open" circle. This means that 5 is excluded.

Answer 32

yes I know that... don't treat me like a dumb ... and
let me tell you something... when things are like this (I thought it was 5 included )

you have to post a photo larger....

Answer 33

Well, that's not my problem ^^

Answer 34

Not mine either... while they don't post questions right... I don't care !

I see a lot of posts like this:

2x2-4x+9=0

if you can't post it like:

\[\Large 2x^2-4x+9=0\]

at least post like this:

2x^2-4x+9=0


(I'm not blaming her for the quadratic equation...)

but if she knew the task was like this, she should have posted a bigger photo !

Answer 36

@inkyvoyd what does that link has to do anything with this ?

Answer 37

Failure of the usage of parenthesis. :)

Answer 38

From what I can see on the number line, the red arrow starts before the 5.
So the answer is "True"
