Just multiply or divide both terms by any number.

For example, multiply each term by 2 to get 36x+18y.

Or, divide each term by 3 to get 6x+3y.

Select the correct answer from each drop-down menu. The general form of the equation of a circle is 7x2 + 7y2 − 28x + 42y − 35 =

nignag [31]

The general form of the equation of a circle is,

x² + y² + Dx + Ey + F = 0, where D, E, F are constants.

The given equation is 7x² + 7y² − 28x + 42y − 35 = 0. So, to convert this equation into a general form we just need to get rid of the leading coefficient 7.

Hence, divide both sides of the equation by 7. So,

$\frac{7x^2+ 7y^2-28x + 42y-35}{7} =0$

x² + y² − 4x + 6y − 5=0.

So, the general form of the equation is x² + y² − 4x + 6y − 5=0.

A decimal rounded to the nearest hundredth is 6.32.This decimal is greater than 6.32

Hi there!

First of all we need to remember the number 6.32.

It could be any of the following:
6.323 OR 6.324

We are rounding UPPP! If you were to round down it would be 6.32 or less.

Hope this helped!
