Why might you want to use thecommutative property to change the order of the integers in the following sum before adding?

Answers

Answer 1

Answer:

Answer :

You can use commutative property or can not be .It is not necessary to use it for given addition of integers.

Step-by-step explanation:

We are given that an expression

$-80+(-173)+(-20)$

By simplfy simply without using commutative property

$-80-173-20=-273$

Because minus minus is plus then all integers will be added.

Simplfy by using commutative property

$-80+(-173)+(-20)$

$-80+(-20)+(-173)$ (Commutative property a+b=b+a)

$-100+(-173)=-273$

The answer should not change .Hence, if you want use commutative property to change the order of the integers then answer does not effected.So, you can use it or can not be .

Answer 2

Answer: u would do this because no matter the order, the answer will be the same

Which statement is true if the degree of the numerator's polynomial function is greater than the degree of the denominator's polynomial function? A. it has one horizontal asymptote. B. it has one vertical asymtote. C. it has no horizontal asymptote. D. it has no vertical asymptote

Answers

If the degree of the numerator`s polynomial function is greater than the degree of the denominator`s polynomial function than:
lim f ( x ) = ∞
x→∞
Answer:
C ) it hasno horizontal asymptote.

Answer:

Option: C is the correct answer.

C. It has no horizontal asymptote.

Step-by-step explanation:

We know that the horizontal asymptote of a function is obtained as follows:

if the degree of the numerator and denominator are equal then we divide the coefficients of the higher degree term.

If the degree of denominator term is greater than the numerator than the horizontal asymptote is the x-axis.

Also if the numerator is of greater degree as compared to the denominator there are no horizontal asymptote.

Hence, in the given question we are given 3) case.

Hence, there are no horizontal asymptote.

Thats simple!
h(x)= $(x^(2)+3x )/(4x+27)$
find h(-8)
All we need to do is PLUG IN THE -8
h(-8)= $((-8)^(2)+3(-8) )/(4(-8)+27)$
= $(64-24)/(-32+27)$ (negative²=positive, negative×positive=negative)
= $(40)/(-5)$
h(-8)=-8
