Which expression is equivalent to 4 over 9 (2n - 3)

AlexFokin [52]

Answer:

The result for this equation is $\frac{8}{9}n - \frac{4}{3}$ .

Step-by-step explanation:

-Solve:

$\frac{4}{9} (2n-3)$

-Multiply $2n$ and $-3$ by $\frac{4}{9}$ :

$\frac{8}{9} + \frac{-12}{9}$

-Reduce $\frac{-12}{9}$ to the lowest term by extracting and canceling out 3:

$\frac{8}{9}n - \frac{4}{3}$

-So, the result is $\frac{8}{9}n - \frac{4}{3}$ .

consider the exponential function f(x)= 1/5(15x) what is the value of the growth factor of the function?

Rus_ich [418]

Answer:

Step-by-step explanation:

The general form of an exponential equation is ...

f(x) = (initial value)(growth factor)^x

That is, the "growth factor" is the base of the exponent. In your equation ...

f(x) = (1/5)(15^x)

the growth factor is 15.

4. I need help with question in the attached picture!

Arisa [49]

ANSWER

D. 13

EXPLANATION

We have

$f(x) = \frac{2x + 1}{x - 4}$

To find

${f}^{ - 1} (3)$

means we want to find an x-value whose image is 3.

$\frac{2x + 1}{x - 4} = 3$

We cross multiply,

$2x + 1 = 3(x - 4)$

Expand:

$2x + 1 = 3x - 12$

Combine like terms,

$3x - 2x = 12 + 1$

$x = 13$

$\therefore{f}^{ - 1} (3)= 13$
