Answer:
It will take 11 minutes per mile
Step-by-step explanation:
If he wants to run all the miles equally, just divide 55 by 5 to get an equal amount of minutes.
a) f(1) = -1 → x = -1
b) g(1) = Undefined
c) f(x) = 1 → x= Undefined
d) g(x) = 1 → x= 5
( z - 5 ) ( z - 5 )
z² − 10z + 25
= z² − 5z - 5z + 25
= z ( z - 5 ) - 5 ( z - 5 )
= ( z - 5 ) ( z - 5 )
