Question

Inequalities....please please help me I don't understand!

Answer 1

is anyone here?

Answer 2

I need to know which inequality matches the picture shown

Answer 3

nanabenyin? I see that you're viewing my question. can you help me?

Answer 4

hey?

Answer 5

hi

Answer 6

Whats the choices? That would help much

Answer 7

can u see that there is a horizontal line drawn on the graph

Answer 8

all of the little "<" ">" things have lines under them

The possible answers are:

x<-1
x>-1
y<-1
y>-1

Answer 9

@Dandave09 yes

Answer 10

desperado can u see a horizontal line drawn

Answer 11

yes

Answer 12

ok now along that line the y coordinate is always -1 so we call that line y=-1. as the shading is done above that line where the y values are bigger. it is y > -1

Answer 13

thank you sooo much! can you help me with a few more?

Answer 14

go for it

Answer 15

it's basically the same thing here

Answer 16

the answers could be:

x>-3
x<-3
y>-3
y<-3

this time the "<" ">" signs don't have lines under them

Answer 17

this time ist is vertical. so it is an x line. you can see every point on that line has an x coordinateof -3 so the line is x=-3. Now the shading is all the x values less than -3 as it is to the left. so x<-3

Answer 18

thank you <3 ! you're a life saver!

Answer 19

can you help me with two more? haha. I'm sorry if this is too much I'm trying to learn though?

Answer 20

go on then
try and tell me what you think the answer is

Answer 21

ok this one is a bit different though

Answer 22

I think the answer is Y<3/2x+3

(The < has a little line under it)

Answer 23

so in this case, how would we find the answer?

Answer 24

ok first of all you need to find the equation of the line, can you do that

Answer 25

what do you mean?

Answer 26

in the graph there is a line yh, that seperates the shadings. so you find the gradient and y-intercept (y=mx+c)

Answer 27

I love solving inequalities

Answer 28

i wish i could but i honestly have no clue how to? lol

Answer 29

The possible answers are:

y<1/3x+3
y<3/2x+3
y>3/2x+3
the correct inequality is not listed


both choice B and C have lines under the signs

Answer 30

desperado you have to find the equation of the line. y=mx+c is the equation of the line. m is the gradient and c is the y-intercept. in ths graph 3 is the y intercept and the gradient is the change in y (3) divided by the change in x (2) so m=3/2 c=3 so y=3/2x+3. Now pick a point (0,0) for example so 0= 0+3 so 0 <3 so u know the enquality is that is that way round. then u pick a point which is on the line and if boths sdes are equal u put the line under th sign. I have to go, hope this helps

Answer 31

thank you! you're brilliant! <3
