(WILL GIVE BRAINLIEST) Which of the following exponential functions goes through the points (1, 6) and (2, 12)?

olganol [36]

Answer:

$\boxed{a. \: f(x) = 3(2)x} \: is \: correct$

Step-by-step explanation:

$if \: the \: points \: are \: (1, 6) \: and \: (2, 12) \to \\ then \to \\ m = \frac{12 - 6}{2 - 1} = \frac{6}{1} \\ \boxed{m = 6} \\ y - 6 = m(x - 1) \\ y = 6x - 6 + 6 \\ y = 6x = (3)(2)x \\ but \: y = f(x) \to \: hence \to \\ \boxed{ f(x) = 3(2)x}$

Does anyone know how to solve this?

masya89 [10]

Answer:

b = -125/9

Step-by-step explanation:

1 + log5 ( -9b) = 4

Subtract 1 from each side

1 -1+ log5 ( -9b) = 4-1

log5 ( -9b) = 3

Raise each side to the base 5

5^ log5 ( -9b) = 5^3

This will cancel the log5

-9b = 125

Divide each side by 9

-9b/-9 = 125/-9

b = -125/9

Which expression represents the quotient of the model shown? -x2 O x + 3 x - 3 lolo o O -X-3 -x + 3

Bess [88]

Answer:

Step-by-step explanation:

Given the expression

-x^2 + x + 3 x - 3

Factorize

(-x^2 + x) + (3 x - 3)

-x(x-1)+3(x-1)

= (x-1)(-x+3)

Hence one of the quotient is -x+3

An animal shelter has 49 dogs and 28 cats . Last week There are 20 cats in the shelter, how many dogs are there ?

blsea [12.9K]

According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.

<u>Explanation:</u>

Let the number of dogs be d and the number of cats be c

If the ratio of dogs to cats is 49:28, then the ratio of d : c would be

$\frac{d}{c} = \frac{49}{28}$

On reducing the fraction, we get

$\frac{d}{c} = \frac{7}{4}$

It is shown that the number of cats is reduced to 20.

So, let the number of dogs after sometime be x

Thus,

$\frac{d}{c} = \frac{7}{4} = \frac{x}{20}$

After cross multiplying we get:

140 = 4x

x = 35

According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.
