Question

HELPPPPPPPPPPP

Answer 1

rewrite the equation so that Y is the function of X

Answer 2

HAAALP I NEED SOMEBODY HELP

Answer 3

no thanks

Answer 4

7x + y = 13

Answer 5

wow are you serious ? that is like first grade stuff...

Answer 6

and 3x + 5y = 15

Answer 7

yeah im serious

Answer 8

sorry im not smart like you

Answer 9

go sheng, you can do it

Answer 10

what you do to one side, you do the other
for example...x + 1 = y is same as x = y - 1

Answer 11

one does not need to be smart to do this

Answer 12

is it y = 7x + 13

Answer 13

negative 7 x you mean?

Answer 14

nope. the sign of 7x should be negative.

Answer 15

wow....

Answer 16

y = -7x + 13 ??

Answer 17

yes justine..

Answer 18

correct

Answer 19

what about 3x + 5y = 15

Answer 20

get the y by itself first of all...

Answer 21

5y = -3x + 15

Answer 22

justine how old are you just asking not trying to be mean

Answer 23

waittt lol

Answer 24

now what do you have to do to 5y to make it y

Answer 25

y = -3x + 3

Answer 26

5y = -3x + 15
isolate the y by dividing it by 5 to both side

Answer 27

you just need to kick out the coefficient of y by dividind each term by 5

Answer 28

even 3?

Answer 29

since when is - 3/5 = - 3?

Answer 30

haha..

Answer 31

justine what grade are you in

Answer 32

The question is "rewrite the equation so that Y is the function of X" with in math language means solve for y because f(x)=y function of x = y

Answer 33

why do you care

Answer 34

justine you wanna a help me find some derivatives using the chain rule combined with some trig rules?

Answer 35

so it's y = 0.6 + 3

Answer 36

-0.6x **

Answer 37

three divided by 5 is three-fifths, justine

Answer 38

hahahaahahhahahaahahahahahahahahahahahahahahahahahahaha

Answer 39

3/5 is 0.6

Answer 40

yes justine

Answer 41

-0.6 will do

Answer 42

hey justine what's the probability that you will pass math this year?

Answer 43

7x + y = 13 subract 7x from both sides and you get: y = 13 - 7x.....done

Answer 44

im getting 89%

Answer 45

hahaha...are you serious ?

Answer 46

yeah??

Answer 47

do you like not try or something just wondering no offense

Answer 48

yeah.. but im not gonna remember all the rules, equations, forms for solving -_-

Answer 49

well there aren't really any rules in these linear functions...its just common sense really

Answer 50

i mean i was doing these in first grade...

Answer 51

good for you then

Answer 52

all you need to know is move the y to one side to isolate it then multiply divide whatever in order to make it = y

Answer 53

i gotta go now, goodnight !!

Answer 54

5y = -3x + 15 divide both side by 5 and y = -(3/5)x + 15/5
y = -3x/5 + 3

internet + trolls = unpleasant......subtract trolls from both sides and internet = more pleasant

Answer 55

thank horrible math

Answer 56

thanks*

Answer 57

i am no troll, i am a legit open study user who helps others

Answer 58

you are so welcome justine <333333

Answer 59

and kantalope

Answer 60

and everyone
