Subtraction of whole numbers is commutative. True or False

strojnjashka [21]

It is False.

If a property is commutative in subtraction it means: x - y is the same as y - x.

For example 5 - 3 = 2, but 3 - 5 = -2 so subtraction is not commutative.

But 5 + 3 = 8 , is the same as 3 + 5 = 8.

Addition is Commutative, but Subtraction is not commutative.

So the statement that subtraction of whole numbers is commutative is False.

Graph y< 1/3 c + 1/2

castortr0y [4]

<h3>The Graph you need above </h3>

<h3>Step-by-step explaination : </h3>

<h3>Combine 1/3and x.</h3>

y<x/3+1/2

<h3>Use the slope-intercept form to find the slope and y-intercept.</h3><h3 />

Slope: 1/3

y-intercept: 1/2

<h3>Graph a dashed line, then shade the area below the boundary line since y is less</h3><h3>than x/3+1/2.</h3>

Use partial fraction expansion to evaluate: LaTeX: \int\frac{x-1}{x^2+3x+2}dx ∫ x − 1 x 2 + 3 x + 2 d x a. LaTeX: -2\ln\left|x+1

ohaa [14]

$\frac{x-1}{x^2+3x+2}\\\frac{x-1}{(x+1)(x+2)}\\\frac{x-1}{(x+1)(x+2)}=\frac{A}{x+2}+\frac{B}{x+1}\\x-1=A(x+1)+B(x+2)\\\\\text{ Let } x=-1 \text{ then } -2=A(0)+B(-1+2) \text{ which means } B=-2\\\\\text{ Instead of choose } x \text{ to be -1, let's now set it equal to -2 to find } A\\\\-3=A(-1)+B(-2+2)\\-3=-A\\A=3\\\\ \text{ So your integral becomes } \\\int \frac{3}{x+2} dx+\int \frac{-2}{x+1} dx\\3 \ln|x+2|-2\ln|x+1|+C\\\\or\\-2\ln|x+1|+3\ln|x+2|+C$
