Answer:
B
Step-by-step explanation:
Because 16 + 2.50 is less than 25 + 0.25x
Answ(0,2)
By putting x 0 and y 2
Step-by-step explanation:
We have been given that the upstream speed is and the down stream speed is .
Let the fisherman traveled a distance of x miles.
The total time of the trip is 6 hours.
Relations between speed (s), time (t) and distance (d) is
Hence,
Time upstream + time downstream = 6
lcm = 10
=>
Cross multiplying,
x = 20 miles .. Answer.
Answer:
f^-1(v)=v/x-3/x
Step-by-step explanation:
-5x(x+3)-7(x-3)/x^2-9= -5x^2-15x-7x+21/x^2-9= -5x^2-22x+21/x62-9
