Real quick question

Answer 1

This question is very simple.

Answer 2

I dont understand these

Answer 3

Alright. I will help you the best I can. Just wait a minute while I solve it then we will go through the steps. :)

Answer 4

Okay, thanks. :)

Answer 5

Anytime.

Answer 6

cops, put 0 in x, 0 in y

Answer 7

2(0) + 0 ? 7

Answer 8

0 <7

Answer 9

Alright. When the sign is facing < way, and the y is on the left of the sign, then y would be less than. Right? So if it was, then y would be less than, so the shaded part of the graph would be going down because if you think about it, the y line is a number line.

Answer 10

It's sort of hard to eplain.

Answer 11

so 0,0 must be shaded,
so 2x+y<7

Answer 12

The answer is not the first one, because y is less than so the shaded part would be upwards if we were following that equation.

Answer 13

So, following my tips, would the solution be 2? Or 3 or 4??

Answer 14

really?
you plug in 0,0 for the first equation, is that true?
then get that equation to slope intercept form to see if the boundary matches.

Answer 15

4???????? Im really slow... and dumb... My brain isnt able to think today...haha D:

Answer 16

It's fine! if you plug in 0,0 and if it turns out that when you plug in 0,0 for x and y, the function would be true, so the shaded part MUST include the origin,(0,0)

Answer 17

Assuming we're just finding the boundary/slope intercept form of the line
2x + y = 7
y= -2x +7
y intercept at 7
slope is -2

Answer 18

I think I got that one thanks guys ... What about this one? Im thinking option c

Answer 19

This is really easy.

Answer 20

Ok cops that's good :)

Answer 21

Yeah you got it!

Answer 22

What about this one?

Answer 23

Im guessing option a??

Answer 24

It would be either 1 or 2 because the line is horizontal.

Answer 25

Yes you got it!

Answer 26

Sweet, thanks a lot : )

Answer 27

Anytime!

Answer 28

oh, I have one moreif thatsok

Answer 29

Sure!

Answer 30

Throw em at me

Answer 31

Alright if you look closely, the line is dotted, am I correct?

Answer 32

Yep ,So it would be one of these > with a line underneath it right?

Answer 33

So that means immediately 3 and 4 would be the wrong answers because if it was greater or less than or equal to, then the line would be solid.

Answer 34

So, no it wouldnt be the ones with < or equal to

Answer 35

So the first option?

Answer 36

Yes! Correct! But let me ask you, why is it option 1? Just so I know that you understand :)

Answer 37

Hmm well I saw the -2 .. and because the > thing was pointing that way, and thats the way the graph was shaded.. if that makes sense

Answer 38

It does!

Answer 39

:) sweet

Answer 40

Alright Glad to help. :)
