ASAAPPPPPP!!!!! Complete the tables of values
velikii [3]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

a^{-m} ⇔ \frac{1}{a^{m} } and a^{0} = 1

Substitute the values of x into 4^{-x}

x = 0 → 4^{0} = 1 ⇒ a = 1

x = 2 → 4^{-2} = \frac{1}{4^{2} } = \frac{1}{16}, hence

b = \frac{1}{16}

x = 4 → 4^{-4} = \frac{1}{4^{4} } = \frac{1}{256}, hence

c = \frac{1}{256}

Х+ Зу = 6<br> бx — бу = 4
Sloan [31]

Answer:

the first one is x= 6-3y or if you are going to solve with the y it will be y =2 - x/3

the second one if you are solving for x it will be x= 2/3 + y if you are solving for y it will be x = 2/3 + x

Step-by-step explanation:

hope this helps

Identify the asymptotes and state the end behavior of the function f(x)=5x/x-25
AnnyKZ [126]

Using it's concepts, it is found that for the function f(x) = \frac{5x}{x - 25}:

  • The vertical asymptote of the function is x = 25.
  • The horizontal asymptote is y = 5. Hence the end behavior is that y \rightarrow 5 when x \rightarrow \infty.

<h3>What are the asymptotes of a function f(x)?</h3>

  • The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.
  • The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity. They also give the end behavior of a function.

In this problem, the function is:

f(x) = \frac{5x}{x - 25}

For the vertical asymptote, it is given by:

x - 25 = 0 -> x = 25.

The horizontal asymptote is given by:

y = \lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{5x}{x - 25} = \lim_{x \rightarrow \infty} \frac{5x}{x} = 5
