. The temperature was 56 degrees this morning but dropped one degree per hour through the rest of the day. Y = - x + 56. (OR, yo

u may use Y = 56 - x. They are the same equation.) Use x-values: 0, 5, and 10.

Y=56-(0) Y=56-(5) Y=56-(10)
= 56 =51 =46

Which of the following is the quotient of the rational expressions shown here? x/x-1 / 1/x 1.

WINSTONCH [101]

The quotient of the rational expressions is $\rm \dfrac{x^2-x}{x-1}$ .

<h3>Given that</h3>

Rational Expression; $\rm \dfrac{x}{x-1}$ ÷ $\rm \dfrac{1}{x+1}$

<h3>We have to determine</h3>

Which of the following is the quotient of the rational expressions shown here?

<h3>According to the question</h3>

Rational Expression; $\rm \dfrac{x}{x-1}$ ÷ $\rm \dfrac{1}{x+1}$

Then,

The quotient of the rational expressions is,

$\rm \dfrac{x}{x-1}$ ÷ $\rm \dfrac{1}{x+1}$

$\rm =\dfrac{x}{x-1} \times \dfrac{x+1}{1}\\
\\ =\dfrac{x(x-1)}{x\times 1}\\
\\
=\dfrac{x^2-x}{x-1}$

Hence, The quotient of the rational expressions is $\rm \dfrac{x^2-x}{x-1}$ .

Aaron, Ruth and Walter created shortcuts for finding the least common multiple of two numbers. Do their methods work for any pai

statuscvo [17]

L.C.M= Least common multiple

If we have to find least common multiple of two numbers

you have to check out which kind of numbers they are.

1. If the numbers are co- prime= Multiply the two numbers

you will get the L.C.M.[Co-Prime numbers→If two numbers doesn't have any common factor then,that two numbers are Co-prime.]

For example L.C.M

(2,3)=2×3=6

(4,5)=4×5=20

(7,9)=7×9=63 So , you can find many more examples.

2. If the two numbers are not Co-prime like (4,6),(8,10)

Then, there is another procedure.

First you have to factorize the two numbers.Then you have to take out common numbers and and then multiply the numbers which are not common with the common number.

For example ,

L.C.M (12,16),

12=2×2×3

16=2×2×2×2

Common numbers are 2×2.

Non common numbers are 3×2×2.

So, L.C.M=2×2×2×2×3=48

Take another example L.C.M(40,80)

40=2×2×2×5

80=2×2×2×2×5

Common numbers=2×2×2×5

Non common number=2

So, L.C.M=2×2×2×2×5=80

If Aaron, Ruth and Walter created this shortcut for finding the least common multiple of any two numbers,then definitely this will work for any pair of numbers.
