what is standard form?

OpenStudy (anonymous):

Standard form is the way you write any number normally. Like writing five thousand and six in stand form would be 5006

OpenStudy (anonymous):

Standard form is a way to write an equation for a graph. Standard form: ax+by+c=0, where a is always positive and the coefficients are integers (that is they are not fractions or decimals)

OpenStudy (anonymous):

Hold on are you talking about standard form as in writing an equation of a line in standard form or writing a number in standard form?

OpenStudy (anonymous):

The "Standard Form" for writing down a polynomial is to put the terms with the highest degree first (like the "2" in x2 if there is one variable).

OpenStudy (anonymous):

well thlve this?? Write the equation y - 2 = 4(x + 5) in standard form

OpenStudy (aripotta):

standard form is Ax + By = C. A cannot be a fraction or a negative number

OpenStudy (anonymous):

um what?

OpenStudy (aripotta):

i gotta walk my dog. i'll explain when i get back!

OpenStudy (anonymous):

It depends on what you want to write the standard form of.

OpenStudy (anonymous):

Write the equation y - 2 = 4(x + 5) in standard form

OpenStudy (anonymous):

Each type of number (numerical expression) or algebraic expression, or equation has its own established 'standard' for how it is written.

OpenStudy (anonymous):

ok but what do i do?? @( confused

OpenStudy (anonymous):

That is a linear equation. The standard form for linear equations is Ax+By=C, where A,B, and C are integers.

OpenStudy (anonymous):

Simplify both sides, the get all your x's and y's on one side and all the constants on the other.

OpenStudy (anonymous):

is x and y changed to a nad b?

OpenStudy (anonymous):

Correction: General Form: ax+by+c=0 Standard Form: ax+by=c Slope-intercept form: y=mx+b

OpenStudy (anonymous):

ok so oh dear i dont get it...

OpenStudy (aripotta):

you're basically moving the x to the left side

OpenStudy (aripotta):

but you have to make sure that the coefficient of x isn't a fraction or negative number

OpenStudy (anonymous):

4x=y-22?

OpenStudy (aripotta):

you have to keep y on the left side

OpenStudy (aripotta):

it's Ax + By = C

OpenStudy (aripotta):

so x and y are on the left

OpenStudy (anonymous):

4x - y = -22 right?

OpenStudy (aripotta):

yup. good job :)

OpenStudy (anonymous):

YAY thank you God bless

OpenStudy (aripotta):

lol no problem

OpenStudy (anonymous):

i got it right on the quiz thanks for heling me understand it!
