Answer:

The answer to your question is Amy is correct.

Step-by-step explanation:

Data

Equation 2x² + 5x - 42 = 0

-Factor

2 x 42 = 84

- Find the prime factors of 84

84 2

42 2

21 3

7 7

84 = 2² 3 7

-Find two numbers that added gives 5

These numbers are 12 and -7

- Express the equation using these numbers

2x² + 12x - 7x - 42

-Factor by common factor

2x(x + 6) -7(x + 6)

-Factor by grouping

(x + 6)(2x - 7)

-Find the roots

x₁ + 6 = 0 2x₂ - 7 = 0

x₁ = -6 2x₂ = 7

x₂ = 7/2

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.
