A regular pentagon shares a common center with a regular hexagon. If `bar(LM)` || `bar(AB)`, across how many lines of reflection
choli [55]

our lines of symmetry is made limited by the presence of the pentagon. If we slice the pentagon into two, the only line of symmetry we could create would be the line intersecting O and the median of LM. Other lines would not create a symmetrical half.

Therefore the line of reflection is only 1.

Let f(x) = x+2/x+6 <br> f^-1(-6) =
GREYUIT [131]

We can explicitly find the inverse. If f^{-1}(x) is the inverse of f(x), then

f\left(f^{-1}(x)\right) = \dfrac{f^{-1}(x)+2}{f^{-1}(x)+6} = x

Solve for the inverse :

\dfrac{f^{-1}(x) + 2}{f^{-1}(x) + 6} = x

\dfrac{f^{-1}(x) + 6 - 4}{f^{-1}(x) + 6} = x

1 - \dfrac4{f^{-1}(x) + 6} = x

1 - x = \dfrac4{f^{-1}(x) + 6}

f^{-1}(x) + 6 = \dfrac4{1-x}

\implies f^{-1}(x) = \dfrac4{1-x} - 6

Then when x = -6, we have

f^{-1}(-6) = \dfrac4{1-(-6)} - 6 = \dfrac47-6 = \boxed{-\dfrac{38}7}

Alternatively, we can first solve for x such that f(x) = -6. Then taking the inverse of both sides, x = f^{-1}(-6). (The difference in this method is that we don't compute the inverse for all x.)

We have

\dfrac{x+2}{x+6} = -6

x + 2 = -6 (x + 6)

x + 2 = -6x - 36

7x = -38

\implies x = \boxed{-\dfrac{38}7}
