Answer:
180= 2x+ 4x+ 3x
180= 9x
x=20
a= 40
b= 80
c= 60
40+60+80= 180 (checking answers)
Step-by-step explanation:
If you were to compress a function vertically by a factor of n, f(x) would change to 1/n * f(x). Thus, choice C is the correct answer.
Trains depart after every 4 minutes.
Total time train takes to complete a circuit= 24 minutes
Evan sets off at 8:30 am, so he will be back at 8:54 am.
So time of trains coming in opposite direction:
8: 34 am
8:38 am
8:42 am
8:46 am
and 8:50 am
5 trains coming in opposite directions.
Now the trains started at 8:06 am from the stations are:
8:06 am
8:10 am
8:14 am
8:18 am
8:22 am
and 8:26 am.
So there are 6 trains started the circuit at 8:06 am.
Now total number of trains=6+5=11 trains
Answer: 11 trains will pass on complete circuit.
It would be D:7
