Question

3. How many solutions does the system of equation have?

3x=-12y+ 15 and + 4y = 5

a. one
b. two
c. infinitely many
d. none

Answer 1

@dtan5457

Answer 2

3x=-12y+ 15
4y = 5

your two equations correct?

Answer 3

3x= -12y+15 and x+4y=5*

Answer 4

Infinite solutions.

isolate y in both equations

12y=15-3x

4y=5-x

divide the first one by 3 and you get the same thing as the 2nd one. same line, infinite solutions

Answer 5

questions?

Answer 6

oh wait!

Answer 7

a. one
b. two
c. infinitely many
d. none

Answer 8

@dtan5457 I forgot to put the answer choices

Answer 9

well exactly i said infinite

so c. infinitely many

Answer 10

oooo okay! I got more questions \(^0^)/

Answer 11

4. how many solutions does the system of equations have

y= 6x + 2
y= 6x + 4

a. one
b. two
c. infinite
d. none

Answer 12

okie. i want you to solve that one. what do you think.

Answer 13

D: don't make meee D:

Answer 14

i can't save you during a real test lol

Answer 15

let me make this easier

Answer 16

okii

Answer 17

I graphed both lines. from what i said yesterday, how many solutions does this graph show?

Answer 18

Do you see them? lol

Answer 19

yes. and it's two lines

Answer 20

@dtan5457

Answer 21

ok...but these lines are parallel.

Answer 22

what does that mean to you

Answer 23

there not intersecting

Answer 24

so many solutions lol

Answer 25

*how many solutions

Answer 26

none?

Answer 27

correct ^

Answer 28

YAYYY

Answer 29

say NONE! not "none?"

NO INTERSECTIONS=NO SOLUTION

Answer 30

NONE!!!

Answer 31

please don't forget that lol

Answer 32

I'll try. but I even had a dream last night that I was taking my algebra Exam and I freaked out

Answer 33

I have more questionssss

Answer 34

lol relax. go ask more questions.

Answer 35

x-\[x-3y=15 and y= \frac{ 1 }{ 3 }x - 5\]

a. one
b. two
c. none
d. infinitely many

Answer 36

@dtan5457

Answer 37

to clarify

your equations:

x-3y=15

y=1/3x-5

Answer 38

yess.

Answer 39

isolate y in the first equation please

Answer 40

x-3y=15

Answer 41

get y alone

Answer 42

try please

Answer 43

o.o you want me to try? okay...

Answer 44

LOL yes. all your questions are pretty much the same. I'm gonna make you do this whole problem, it's really not that hard once you get the concepts

Answer 45

you don't have school tomorrow correct?

Answer 46

correct but I've been doing this math literally all day and I'm almost doneee D:

Answer 47

6 more questionsssss D:

Answer 48

did you do them without my help lol

Answer 49

if you knew how to do these problems you'll do your last 6 questions in under 10 minutes..

Answer 50

by yourself lol

Answer 51

UGHHH HYKFJNKJNEKJ I did the others with desmo but then I realized I couldn't do these with desmos and now Im screweddd D:

Answer 52

actually you can do them with desmos as long as you isolate y

Answer 53

isolate y missy

Answer 54

shhhhh let's act like I can't D:

Answer 55

shhhh shhhh

Answer 56

I hate math -.-

Answer 57

I got a question...(im sorry im done and I forget things) but how do I get y alone again?

Answer 58

x-3y=15 put y on one side of the equal sign with the other terms to the other side. if your gonna remove the x you subtract it so don't forget the negative sign

Answer 59

oh yeah, and just a hint these are linear equations there will never be 2 solutions its either 1, none, or infinite

Answer 60

so right now let me see your equation after you isolated y please

Answer 61

oohhh kkkk

Answer 62

well *nervously laughs* about go isolate that y mhm okay

Answer 63

look if i told you

5+5=10

i can switch this equation however i want, i can subtract 5 on each side and still get
5=5

Answer 64

oh because 10-5 is 5

Answer 65

YES

Answer 66

so for x-3y=15

Answer 67

in what way is y not alone

Answer 68

hint: there's a frickin x right in front of it

Answer 69

remove it mate

Answer 70

wait so am I subtracting 15 on each sides? (sorry, stupid question OMG IM SO SORRY FOR BEING STUPID. LIKE OMG IM SORRY LIKE SORRY IM SORRY)

Answer 71

*is a failure*

Answer 72

you could but it just makes it more confusing

x-3y=15 remove the x

SUBTRACT THE X

Answer 73

how do you subtract x? like actually put x- 15??? or am I putting x-3?? AHHHHHHH

Answer 74

x-3y=15
-x -x

=???

Answer 75

*runs around in circles*

Answer 76

okay hold on

Answer 77

wait do I put this in desmo?

Answer 78

o.o

Answer 79

you're probably facepalming yourself in real life omg

Answer 80

i just asked you to subtract x and give me the equation

Answer 81

why do you find that confusing lol

Answer 82

its as simple as the instructions

Answer 83

I know ! I know lol like but where do I subtract at? a Calculator? desmo?
just take x away like 3y=15? D:

Answer 84

ok WATCH KID

EXAMPLE X+Z+C+A+D=0

ISOLATE X I HAVE TO REMOVE THE OTHER VARIABLES

X=-Z-C-A-D

therefore i just SUBTRACT it to the other side. i dont see a need for a calculator

Answer 85

...

Answer 86

._. sorry.

Answer 87

x-3y=15
-x -x

=-3y=15-x

Answer 88

can you see that mate

Answer 89

yes I see it ._.

Answer 90

y=1/3x-5

Answer 91

how do i isolate y here, please tell me you can tell me something here

Answer 92

hint: its a trick question

Answer 93

if this takes you more than 1 min then you didn't get my concept lol

Answer 94

more than 1 millisecond

Answer 95

sorry my wifi is like acting stupid

Answer 96

its ok but y=1/3x-5

how do i isolate y

Answer 97

you um you put the y on the other said? =-5-y?
