It is obvious that the radicals with negative sign tends to be less than those that are positive. So from there you already know a basic order. Now to be sure, you can use a calculator or just solve by squaring the whole number to find the radical form.
F(x) and g(x) were inverse functions, then if f(a) = b, then g(b) = a
f(x) = (5x+1) / x g(x) = x / (5x+1)
f(1) = 6, but g(6) = 6/31 ≠ 1
So, f(x) and g(x) are NOT inverse functions.
500/20 = 25kcal per piece
8 * 25 = 200kcal.....yes, he is able to have 8 pieces
I need to see a picture of the question so I can answer the question:)
The question isn’t clear, can you write it better so I can understand?
