Answer:

The first fraction is between 27 and 28, closer to 28. The second fraction is between 3 and 4, closer to 4. Compatible numbers in division are numbers that can be divided mentally. 28 divided by 4 is 7. The quotient will be around 7.

Answer:

The fraction 27 and two-thirds are between 27 and 28, closer to 28.

The fraction 3 and StartFraction 9 over 10 EndFraction is between 3 and 4, closer to 4.

Compatible numbers are easily divided.

By changing the numbers to 28 and 4, you can use the division 28 ÷ 4 = 7.

Which of the following functions have only one point that is not in the domain? Select all that apply. (There are 2 answers)
densk [106]

Answer:

  B.  f(x) = 3/(x^2 +2x +1)

  E.  f(x) = 5/(3+x)

Step-by-step explanation:

The above functions have denominators that are zero at one point. For B, that point is x=-1; for E, that point is x=-3. When the denominator is zero, the function is undefined, so the corresponding x-value must be excluded from the domain.

__

As written, choice D also qualifies. This is because the function written in the answer list here is ...

f(x)=\dfrac{1}{x^2}+5x+4

It will be undefined for x=0.

_____

<em>Comment on writing rational functions</em>

When the division symbol (/ or ÷) is used with a denominator that is a product or sum, that product or sum must be enclosed in parentheses. When the expression is typeset, the division bar acts as a grouping symbol. When the expression is written in text, a grouping symbol, such as parentheses, must be added.

Preform the subtraction: (5x^2 -3xy +10y^2) - (12x^2 +11xz- 7z^2)
Rzqust [24]

we are given

(5x^2 -3xy +10y^2) - (12x^2+11xz-7z^2)

we have to subtract

step-1:  Distribute negative sign

=5x^2 -3xy +10y^2-12x^2-11xz+7z^2

step-2:Combine like terms

=5x^2 -12x^2-3xy -11xz+10y^2+7z^2

=-7x^2-3xy -11xz+10y^2+7z^2

we get

=-7x^2-3xy -11xz+10y^2+7z^2............Answer
