Question

Write the following linear function in the form Ax+By=C.

1. y=3/4x-1

2. 2y=-5/3x+4

Answer 1

\[y=\frac{ 3 }{ 4}x-1\]\[y+(\frac{ 3 }{ 4}x)=\frac{ 3 }{ 4}x=(-\frac{ 3 }{ 4}x)-1\]\[y-\frac{ 3 }{ 4}x=-1\]\[-\frac{ 3 }{ 4}x+y=-1\]
\[\frac{ 3 }{ 4}x-y=1\]
Can someone check my answer if correct.?????

Answer 2

correct..
carry on...

Answer 3

Yes, that is right. A, B, and C can be positive or negative, so as you have solved it A=3/4. B=-1, and C=1.

Answer 4

\[2y=\frac{ -5 }{ 3}x + 4\]
\[2y +\frac{ 5 }{ 3 }x=4\]
\[5x + 6y = 12\]

Answer 5

that would be for #2

Answer 6

\[2y=-\frac{ 5}{ 3}x+4\]\[2y+(\frac{ 5 }{ 3}x)=-\frac{ 5 }{ 3}x+(\frac{ 5 }{ 3})+4\]\[2y-\frac{ 5 }{ 3}x=4\]\[-\frac{ 5 }{ 3}x+2y=4\]
\[\frac{ 5 }{ 3}x-2y=-4\]
help please. check my answer .?

Answer 7

yes you are correct

Answer 8

Yes but you need to multiply the whole thing by 3 to eliminate the fractions
5x-6y=-12

Answer 9

can you do it for me . ? I don't get your point.???

Answer 10

i already showed you a example

Answer 11

I mean the whole solution . Can you do it ? please?

Answer 12

no you are correct all the way were just telling you to multiply by 3 so you can cancel out the fraction.

Answer 13

you distribute a 3 to each term
3( (5/3)x-2y)=3(-4)
5x-6y=-12

all of your work is correct but standard form is usually whole numbers for A and B

Answer 14

as in multiply ? not in divide?

Answer 15

distributive property is basic property in mathematics
it means to multiply

Answer 16

ahh. ok i will try.

Answer 17

its pretty confusing in the beginning but it will get easier once you understand

Answer 18

Ok i get it thanks...! :)

Answer 19

So the final answer is 5x_6y+-12 ??

Answer 20

5x-6y=-12 ?

Answer 21

yes

Answer 22

no wait

Answer 23

no its wrong

Answer 24

huh. ?

Answer 25

you made a mistake in your work

Answer 26

why?

Answer 27

what is it?

Answer 28

5x+6y=12

Answer 29

well you did from this \[2y + (\frac{ 5 }{ 3 }x) = -\frac{ 5 }{ 3 }x+(\frac{ 5 }{ 3 }x) + 4\]
to \[2y -\frac{ 5 }{ 3 }x = 4\]

Answer 30

I think you changed a sign along the way

Answer 31

and then so on

Answer 32

but the answer is what precal said

Answer 33

5x+6y=12 .is the final answer?

Answer 34

thank you so much my friends , FriedRice and precal ... :)

Answer 35

anytime
