Answer:

f^-1(x) = √(6/(9 -x))

Step-by-step explanation:

The inverse function is the solution to ...

x = f(y)

x = 9 -6/y^2

x +6/y^2 = 9 . . . . . add 6/y^2

6/y^2 = 9 -x . . . . . subtract x

6/(9 -x) = y^2 . . . . . multiply by y^2/(9 -x)

y = √(6/(9 -x)) . . . . take the square root

Then the inverse function can be written as ...

f^-1(x) = √(6/(9 -x)) . . . . . . x < 9

-6x is less than or equal to 4x+2

kicyunya [14]

-6x <= 4x + 2
Subtract 4x from both sides
-10x <= 2
Divide -10 on both sides
Final Answer: x >= -1/5

(15x2 – 24x + 9) ÷ (3x – 3)

dsp73

$\bf 15x^2-24x+9\div 3x-3\implies \cfrac{15x^2-24x+9}{3x-3}\implies \cfrac{\underline{3}(5x^2-8x+3)}{\underline{3}(x-1)}
\\\\\\
\cfrac{5x^2-8x+3}{x-1}\implies \cfrac{(5x-3)\underline{(x-1)}}{\underline{(x-1)}}\implies 5x-3$

-1/2x+2=-x+7 i need to know

ludmilkaskok [199]

$= \frac{ - 1}{ \: \: 2} x + 2 = x + 7$

$= \frac{ - 1}{ \: \: \: 2} x + 2 - x = 7$

$= \frac{ - 3}{ \: \: \: 2}x + 2 = 7$

$= \frac{ - 3}{ \: \ \: 2}x = 7 - 2$

$= \frac{ - 3}{ \: \: \: 2} x = 5$

$x = 5 \: \div \frac{ - 3}{ \: \: \: 2}$

$x = 5 \times \frac{ \: \: \: 2}{ - 3}$

$x = \frac{ - 10}{ \: \: \: 3}$

$∴ \frac{ - 1}{ \: \: \: 2} \times \frac{ - 10}{ \: \: \: 3} = \frac{ - 10}{ \: \: \: 3} + 7$
