Determine whether f(x)=5x+1/x and g(x)= x/5x+1 are inverse functions. Explain how you know.
vladimir1956 [14]
A property of inverse functions is that if f(x) = a, g(a) = x

F(x) = (5x+1)/x
G(x) = x/(5x+1)

Plug in x = 3.
F(3) = 16/3
G(16/3) = 16/83. Since it doesn’t equal 3, it’s not an inverse function

Bobby is making ornaments for christmas to sell. He is selling ornaments for $9.00 each. He also just receive ed a check for $28
pentagon [3]

Answer: $217.

Step-by-step explanation:

So he starts with 28 dollars. We want to find out how much total he makes. To do so we multiply 21 by 9 because he sells 21 ornaments at $9. 21 x 9 = 189. 189 + 28 = 217. So with the $28 from the start, he made $217.
