Bring the fraction a/a−4 to a denominator of 16−a^2<br><br> really do appreciate this thx
RSB [31]

Answer:

-a(a+4)/(16 - a²)

Step-by-step explanation:

            a/(a - 4)                  Multiply by (a + 4)/(a + 4)

= a(a + 4)/[(a – 4)(a + 4)]     Multiply the denominatorator terms

= a(a + 4)/(a² - 16)               Multiply by -1/(-1)

= -a(a+4)/(-a² + 16)              Reorder terms in denominator

= -a(a+4)/(16 - a²)

FrozenT [24]

Answer:

1. Quantitative

2. Quantitative

3. Qualitative

4. Qualitative

5. Quantitative

Step-by-step explanation:

A variable is quantitative if it assumes numerical values, for example 1,2,3.

If it assumes "labels", for example good or bad, it is qualitative.

1. Rating of the quality of a movie on a 7-point scale

It assumes numerical values, for example, 1,2,3,...

So it is quantitative

So it is quantitative

3. Country you were born in

Descriptive, such as Brazil, USA, Colombia, ...

So it is qualitative.

4. Favorite Color

Descriptive, such as black, brown, red, blue

So it is qualitative

5. Time to respond to a question

It assumes numerical values, for example, 1,20,35,...

So it is quantitative

FAST ANSWER PLEASE THANKS
Citrus2011 [14]

Answer:

(f • g)(x) = x² - 6x + 7

Step-by-step explanation:

Suppose

f(x) = x² - 2

g(x) = x - 3

Determine

(f • g)(x) = ...

We can compose the functions by doing the following

(f • g)(x) = f(g(x))

(f • g)(x) = f(x - 3)

(f • g)(x) = (x - 3)² - 2

(f • g)(x) = x² - 6x + 9 - 2

(f • g)(x) = x² - 6x + 7

I hope this helps!
