For which pairs of functions is (fog)(x)=x?

f(x) = x2 and g(x) = 1/x

f(x) = 2/x and g(x) = 2/x

f(x) = x-2/3 and g(x) = 2-3x

f(x) = 1/2 x-2 and g(x) = 1/2 x+2

What is the binomial expansion of (2x-3)^5

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
