A and b are positive integers and a - b = 2. Evaluate the following: 3b/3а

AlexFokin [52]

Answer and Step-by-step explanation:

a - b = 2

$\frac{3b}{3a}$ = $\frac{b}{a}$

b = a - 2

a = b + 2

______________

b = b + 2 - 2

b = b

______________

a = a - 2 + 2

a = a

______________

If a equals 0, then the expression is undefined.

If b = 0, then the expression is 0.

There are infinite number of solutions when a is not 0 and the numbers are positive.

If f(x) = 2/3x + 9, find f^-1(x)

larisa86 [58]

If $f^{-1}(x)$ is the inverse of

$f(x) = \dfrac23x+9$

then

$f\left(f^{-1}(x)\right) = \dfrac23f^{-1}(x) + 9 = x$

Solve for $f^{-1}(x)$ :

$\dfrac23f^{-1}(x)+9 = x \\\\ \dfrac23f^{-1}(x) = x-9 \\\\ f^{-1}(x) = \dfrac32(x-9) = \dfrac32x-\dfrac{27}2$

which makes D the correct answer.
