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
16/ 2.10 = 7.6 ounces per $1
20/ 3.15 = 6.3 ounces per $1
So which do you think?
P(n)=news time/total time
We are told that the news is 14 minutes long during an hour so
p(n)=14/60
p(n)=7/30
5 24
- -
8 1
Simplify 24 and 8. (8 goes into 24 six times.)
5 6
- -
1 1
or
5 x 6 = 30
