hi!!:):)

Answer 4

helpme please @123AB456C

Answer 6

You can substitute.... So we can input the points for answer A....\[4\le-2(0)+3\]We need to make sure that our total on the right side is great than or equal to 4...

Answer 7

how does this work

Answer 8

B. \[0 \le -2(1)+3\]

C. \[-2\le-2(3)+3\]

D.\[-2 \le -2(5)+3\]

Answer 9

the answer is Bjust plug in the x nad y values an see if they make the inequality true :-)

Answer 10

well.. have you tested the given choices yet?

Answer 11

I think it b or a

Answer 12

@cowgirl1 you can not give away the answer to the openstudier it is against the code of conduct....

Answer 13

b or a? how so?

Answer 14

wait its not b or a
I did it on my paper
I think its c

Answer 15

sorry I ddint know..i saw replies that way and thougt it was ok

Answer 16

c? how did you get c?

Answer 17

Answer 19

@jdoe0001 wow I can see how that is related :)....if heard of that quote before ^^

Answer 20

i've *

Answer 21

ive seen it too...and again im sorry

Answer 22

can some please explain me how to do this
im cofused

Answer 23

gimme a sec... lemme show you using A) choice

Answer 24

ok on one side you have y and on the other you have x. the coordinates given are (x,y) if you fill in the values of x and y from the coordinates given into the inequality, you can check to see if the inequality is true

Answer 25

You would use the points and substitute where correspond with.... the points are set like this (x,y) so we would input the numbers where each go....

ex. You are given (0,3)

You have the eqaution y<2x+4

You would input 3 where y is and 0 where x is...

3<2(0)+4

Answer 26

And its alright @cowgirl1 ^^

Answer 27

hmmm hold the mayo a sec....lemme fix that.. I got the letters swapped shoot

Answer 28

and thank you @563blackghost ...i wont do that again

Answer 29

\({\color{brown}{ y}}\le-2{\color{blue}{ x}}+3\qquad \qquad
\begin{array}{llll}
A)&0&,&4\\
&x&&y
\end{array}
\\ \quad \\ \quad \\
{\color{brown}{ 4 }}\le-2{\color{blue}{ (0)}}+3\implies 0\le 0+3\implies 4\le3\)

so.. is that really true? is \(4\le 3?\)

Answer 30

so.. what do you think @gigiheart63 ... is that true? is really \(\large 4\le 3?\)

Answer 31

shoot....I have a typo... but the result is correct... anyhow \({\color{brown}{ y}}\le-2{\color{blue}{ x}}+3\qquad \qquad
\begin{array}{llll}
A)&0&,&4\\
&x&&y
\end{array}
\\ \quad \\ \quad \\
{\color{brown}{ 4 }}\le-2{\color{blue}{ (0)}}+3\implies 4\le 0+3\implies 4\le3\)

Answer 32

yes idk

Answer 33

yes? idk? which is it? lemme put it this way

is 4 Greater, or bigger than 3?

if you have 4 oranges, as opposed to 3 oranges
is 4 more than 3?

Answer 34

or is 3 more than 4
or 4 is less than 3?

would you rather have 3 oranges instead?

Answer 35

or would you rather have avocados and chips =)

Answer 36

4 is greter its
its false

Answer 37

ahah.... see... now we know A) choice is false, because, yes, you're correct
4 is "more" or greater than 3 thus \(\large 4\bcancel{\le} 3\)

so... now.. .try the others... say B)

\({\color{brown}{ y}}\le-2{\color{blue}{ x}}+3\qquad \qquad
\begin{array}{llll}
B)&1&,&0\\
&x&&y
\end{array}
\\ \quad \\ \quad \\
{\color{brown}{ 0 }}\le-2{\color{blue}{ (1)}}+3\implies ?\)

Answer 38

anyway... check the given choices... see which one gives you true :)

Answer 39

please close your question once you have gotten your answer ^^

Answer 40

Wait so you got your answer answered???

Answer 41

By far the simplest way to identify a solution to \[y \le-2x+3\]

Answer 42

is to substitute the coordinates of each given point and determine whether the resulting inequality is true or false.

A(0,4) has x=0 and y=4.

Is this true or false?

\[4\le-2(0)+3\]

If true, then A is a solution; if false, then A is not a solution. Do the same thing in the case of the other 3 possible solutions.
