Rounding is a handy tool in the business world for working with amounts. Its a lot easier to work with values when they have values rounded to the nearest ten, hundred, etc. So it is basically going to be part of our everyday lives. Hope I helped!

Simplify 24x5 y6 . A) 2x2 y3 6x B) 4x2 y3 6x C) 6x2 y3 4x D) 6x2 y3 2x

Cerrena [4.2K]

Answer : A $2x^2y^3\sqrt{6x}$

$\sqrt{ 24x^5y^6}$

Take square root for each term and simplify it

$\sqrt{24} *\sqrt{x^5} *\sqrt{y^6}$

$\sqrt{24}=\sqrt{4 * 6} = 2\sqrt{6}$

$\sqrt{x^5} = x^2\sqrt{x}$

$\sqrt{y^6} = y^3$

so we will get

$2\sqrt{6} * x^2\sqrt{x} * y^3$

$2x^2y^3\sqrt{6x}$

20y-10x=5 in slope intercept form can you explain the steps

Studentka2010 [4]

Given:

The equation is

$20y-10x+5$

To find:

The slope intercept form of the given equation.

Solution:

The slope intercept form of a linear equation is

$y=mx+b$

Where, m is slope and b is the y-intercept.

We have,

$20y-10x=5$

We need to isolate y. Add 10x on both sides.

$20y-10x+10x=5+10x$

$20y=5+10x$

Divide both sides by 20.

$\dfrac{20y}{20}=\dfrac{5+10x}{20}$

$y=\dfrac{5}{20}+\dfrac{10x}{20}$

$y=\dfrac{1}{4}+\dfrac{x}{2}$

$y=\dfrac{1}{2}x+\dfrac{1}{4}$

Therefore, the slope intercept form of the given equation is $y=\dfrac{1}{2}x+\dfrac{1}{4}$ .
