Question

If the linear equation 2x = 9 − 3y is written in standard form, what is the value of B?

Answer 1

what is "standard form"?

Answer 2

Add 3y to both sides...

Answer 3

i still want to know what standard form is

Answer 4

Satellite, I don't really think there's an agreed upon convention about "Standard form" of a linear equation.

Answer 5

STANDARD FORM
Like from expanded form, EX: 3,000+200+50+4

You wouldn't put standard form this way. EX: 3,000200504

that's a NO. 3,000200504


You change it to standard form, EX: 3,254

Or from expanded notation,EX: (3.1,000)+(2.100)+(5.10)+(4.1),


Again you wouldn't put it this way EX: (3.1000)(2.100)(5.10)(4.1)

That's a NO WAY. (3.1000)(2.100)(5.10)(4.1)


You can change it again to EX: 3,254

Or from word form, EX: three thousand two hundred fifty-four

You can change it the third time to EX: 3,254

Lastly for now, from short word form, EX: 3 thousand 2 hundred 54

You can change it to lastly 3,254.

Did this help?

Answer 6

http://en.wikipedia.org/wiki/Linear_equation#Standard_form
Wikipedia says that it's
Ax+By = C

Answer 7

Lol I was correct then :D

Answer 8

But I say screw that. That's the least useful way to write a line evah.

Answer 9

A. Standard Form
---------------
1-Ax + By = C
2-A, B, C are integers (positive or negative whole numbers)
3-No fractions nor decimals in standard form.
4-Traditionally the "Ax" term is positive.
______________________________________________________________________
How to Write the Equation into Standard Form When Given an Equation:
__________________________________________
{{{{If there are fractions:}}}
Multiply each term in the equation by the LCD.
Add or subtract to get “x” and “y” on the same side and the number term on the opposite side.
{{{If there are decimals}}}
Multiply each term in the equation by 10, 100, 1000, etc.
Add or subtract to get “x” and “y” on the same side and the number term on the opposite side.
{{If there are no fractions nor decimals:}}}
Add or subtract to get “x” and “y” on the same side and the number term on the opposite side.

Answer 10

I still dont know what the answer is .................... lol

Answer 11

"But I say screw that. That's the least useful way to write a line evah."
I think it is usefull. Vector (A,B) is a normal vector to the line, and what equation says it's that the projection of the position vector (x,y) of the points that belong to the line is constant and equal to C. Also has meaning for the points (x,y) not on the line, give the distance to it. So i think it's preaty useful @SmoothMath

Answer 12

phft lol ^

Answer 13

answer is 3

Answer 14

thank-you myko!
