Answer: 16) $\bold{\sqrt{x}}$ (17) $\bold{\dfrac{x-4}{2}}$ (18) $\bold{\sqrt{x}-2}$ (19) 3x - 18

<u>Step-by-step explanation:</u>

Inverse is when you swap the x's and y's and then solve for y

16) Given: y = x²

Swapped: x = y²

$\bold{\sqrt{x} =y}$

17) Given: y = 2x + 4

Swapped: x = 2y + 4

x - 4 = 2y

$\bold{\dfrac{x-4}{2}=y}$

18) Given: y = (x + 2)²

Swapped: x = (y + 2)²

√x = y + 2

$\bold{\sqrt{x}-2=y}$

19) Given: $y=\dfrac{1}{3}x+6$

Swapped: $x=\dfrac{1}{3}y+6$

$x - 6 = \dfrac{1}{3}y$

3(x - 6) = y

3x - 18 = y

What is the simplest form of x²+5x-6/x²+9x+18

Lyrx [107]

Answer:

(x - 1) / (x + 3).

Step-by-step explanation:

x²+5x-6/x²+9x+18

Factoring top and bottom:

= (x + 6)(x - 1) / (x + 6)(x + 3) (x + 6) is common, so:

= (x - 1) / (x + 3) (answer).
