Question

Choose the point which is a solution to the system of inequalities:

4x + 3y > 12
x – y –2

Choices:
A.(2, 1)
B.(–5, –6)
C.(–4, 9)
D.(3, 7)

Tell me how to solve it and the answer please

Answer 1

what's the second inequality?

Answer 2

the points are (x,y). So for ur first point, 2 is x and 1 is y.
plug them into your first inequality and see if they work.

Answer 3

oh it's less than or equal to

Answer 4

\[x-y \le -2 ?\]

Answer 5

then you should plug it into your second and see if it works there.

so it's x-y is less than or equal to 2?

Answer 6

\[x-y \le 2?\]

Answer 7

yeah thats it

Answer 8

the second one?

Answer 9

yeah but instead of the 2 its -2

Answer 10

so the first one?

Answer 11

\[x-y \le -2\]

Answer 12

k. so ,first equation w/first point-
4(2)+3(1)>12
8+3>12
11>12
no
so the first point isn't it

Answer 13

go through the choices and see what which of the choices satisfy the system of inequalities

Answer 14

second point-
4(-5)+3(-6)>12
-20-18>12
-38>12
no again

Answer 15

third-
4(-4)+3(9)>12
-16+27>12
11>12
no

Answer 16

he is saying no this point won't work because 11>12 is not true
and -38>12 is not true so he
has pointed out so far (2,1) and (-5,-6) will not work

Answer 17

it has to be the last one by process of elimination, but we'll work it through.
4(3)+3(7)>12
12+21>12
33>12
yes

Answer 18

hello myininaya

Answer 19

hey

Answer 20

ok i got it thank you :)

Answer 21

i wanted to tell you that yesterday some one wanted to solve a quadric equation

Answer 22

needhelp you have to see if it works for both inequalities

Answer 23

and they say
"can we use the Method of Myininaya" that i heard about?"

Answer 24

lol

Answer 25

method of myininaya! really

Answer 26

i got another question

Answer 27

don't forget to put it through the second system too-
x-y<or equal to 2
3-7<equal2
-4<equal 2
yup

Answer 28

sure! we'll help!

Answer 29

ok here it is

Answer 30

so it still would for
-4<equal -2
which ever one you had

Answer 31

lol

Answer 32

Choose the system of inequalities that matches the graph below

Answer 33

and here are the choices

Answer 34

A)2x – 3y > –27
x + 5y < 15

B)2x – 3y < –27
x + 5y < 15

C)2x – 3y –27
x + 5y 15

D)2x – 3y –27
x + 5y 15

Answer 35

inequality signs are missing last 2 answers

Answer 36

pretty sure one of the lines is y>2/3 x+9... now just need to see what form it's in here...

Answer 37

I mean y<

Answer 38

oh choice 2 is 2x-3 greater than or equal to -27
and x+5y less than or equal to 15

Answer 39

its look at the lines
first lets look at the one with positive slope
it has y intercept 9
and rise over run is 2/3

so that line would be y=2x/3+9

now lets look at the second line that has negative slope
it has y-intercept 3
and rise over run is -1/5

so that line would be y=-x/5+3

now lets look at the inequality part

Answer 40

y<-1/5 x+3 is ze second...

Answer 41

choice 3 is 2x – 3y Less than or equal to –27 and
x + 5y less than or equal to 15

Answer 42

both lines are broken so we don't have = signs
both should have less than sign
and gandalf gots it

Answer 43

now put in the form they have it in and you will find your answers

Answer 44

yeah i just gave you the signs for each

Answer 45

oops that first one should have a less than sign

Answer 46

-2x+3y<27

Answer 47

y<2x/3+9
3y<2x+27
-2x+3y<27

Answer 48

so the answer is B?

Answer 49

2x-3y>-27
x+5y<15

Answer 50

oooooh its A

Answer 51

thank you so much again :)
