Question

medal to anyone that helps

Match each system of linear equations with the
quadrant in which the solution lies.
3x + 2y = 14
x - 3y = -10

2x + 3y = -12
4x - 2y = -2

3x - 2y = 10
5x + 3y = 4

x + 2y = 8
4x + 6y =22

Answer 1

anyone there

Answer 2

Hi there!

Answer 3

can you help me

Answer 4

For these I would solve for x or y than do substitution for the variable you solved or, you could also do the elimination method, getting the x or y's to cancel and and than getting an answer for x or y and plugging that back in into one of those variables to find the other one

Answer 5

I can explain both ways for you on any number you want

Answer 6

can you help with all them plz

Answer 7

Sure, i'll do substitution for 2 and elimination for 2 if thats okay so you know two ways, elimination is my favorite personally

Answer 8

you will do all them in two ways

Answer 9

3x+2y=14
x-3y=-10
Would you like to figure out x or y?
Me personally I would do x for the bottom because all you have to do is add 3y to both sides, but its your choice

Answer 10

I just want to get the question thx tho

Answer 11

Thats how you have to do it though, otherwise it will take way to long to try and find the coordinates that work for both equations

Answer 12

Unless you get lucky

Answer 13

ok thx this is all new to me

Answer 14

Have you learned the substitution or elimination method?

Answer 15

You would have to cancel one of the variables for elimination its much easier than substitution and takes way less time

Answer 16

I think but when you solve the problems I understand

Answer 17

Okay, if you wanna try number one if you think you can let me know what you get and I'll tell you what I get if you don't know where to start i'll help

Answer 18

I don't know how to do this its why I put it in this site

Answer 19

Okay so 3x+2y=14
X-3y=-10
So you would have to mutiple the bottom by -3 the whole function, because than the x's would cancel so you would have 2y=14 on the top on and -3(-3y)=-3(-10)
So than you will have 2y=14 on the top and 9y=30 and you add those values so you will have 11y=44 than divide by 11 so y=4 and than plug 4 in for 4 so 3x+2(4)=14 so than 3x+8=14 subtract 8 3x=6 x=2 so your coordinate is (2, 4) so the coordinate is in the first quadrant

Answer 20

Making use of Kayder's suggestion, and multiplying the 2nd equation by -1, we get

first equation: 3x + 2y = 14
-3x+ 9y = 30
-------------

Please add these two equations together, column by column. What's left? ( ? ) y = ( ? )

Answer 21

thx are you guy and girl going to help with the others? plz

Answer 22

I'd be glad to help after you've started each problem and gone as far as you can before getting stuck. At that point, ask questions!

Answer 23

Same, I wanna be a math teacher so I would love to help you

Answer 24

i want to help you pup02

Answer 25

ok you all can help I just don't get this sorry

Answer 26

If it was on paper would that help more?

Answer 27

idk

Answer 28

iam sorry , iam not very good in english so, please tell me what do you want exactly for the previous equations

Answer 29

You camt add pictures shoot

Answer 30

what are the other three

Answer 31

Do you still need help on the first part?

Answer 32

Where you have to multiply

Answer 33

To eliminate a variable

Answer 34

I got the first one I just need you to do the other three problems

Answer 35

2x+3y=-12
4x-2y=-2 what would you have to multiply to the top to get opposites for x's

Answer 36

Opposites signs, but same number so basically get -4x

Answer 37

you want to know what are x and y equal at all the three equations?

Answer 38

what quadrant the solution is in

Answer 39

so it would be in the third quadrant

Answer 40

yes i understand

Answer 41

That depends on what you get for x and y if you get positive for both you get quadrant 1 if x is negitive and y positive than its quad 2 if they are both negitive than quad 3 if y is negitive and x is positive than y is negitive than it is quad 4

Answer 42

But you first have to do that elimination method

Answer 43

so pup let me solve it for you . to know which quadrant we must get the values of x and y
so in the first problem x=3.2 and y=4.4 so it will be at quadrant 1

Answer 44

that is for the first quastion

Answer 45

yes

Answer 46

No

Answer 47

Plug it back i to both equtions you dont get those answers

Answer 48

for the equations 3x+y=14
x-3y=-10

Answer 49

ok what are the other three

Answer 50

The answer is x=2 y=4

Answer 51

ok what is the answer for the second answer.

Answer 52

yes you are right because i have seen the first equation 3x+y=14

Answer 53

so the answers are for the first problem x=2 y=4 an the quadrant 1
for the second problem x=-15/8 y=-11/4 and the quardant is 3

Answer 54

ok that's really is great thanks for helping me

Answer 55

what is the third question

Answer 56

if you want any help contact me anytime

Answer 57

the third is x=2 y=-2 in the quadrant 4

Answer 58

thank you

Answer 59

2x + 3y = -12
4x - 2y = -2
Okay for this equation you would multiply the top by -2 so than -2(2x+3y equal -12) so than you will have -4x+-6y=24 and the bottom equation would stay the same so now you add -4x+4x=0 And -6y +-2y =-8y and 24+-2=22 so than -8y=22 so than it will be 22/-8 which can be reduced to -11/4 and than plug that into y and than it will be 2x=+3(-11/4) =-12 so 2x-33/4=-12 so add 33/4 so 2x=2x=-15/4 than divide by 2 so x=-15/8 so both x and y are negitive so than you will be in quadrant 4

Answer 60

quadrant 3 my bad

Answer 61

haha thank you all
