Answer:
3:15 pm
Step-by-step explanation:
You can imagine that they go in a circle (we can do whatever we want in theoretical math and physics). By doing so we know we can obtain a cosinusoidal wave by projecting the motion on a plane. Each one of the buses has a period (minimum time after what they're in the same point again). For the first one it's 15 minutes, for the second one it's 20 minutes. We have to take the least common multiple of the periods, that is 75 minutes. So They'll meet every 75 minutes. Add 75 minutes (1h and 15 minutes) to 2pm and there you go.
A) (-2,4)
first multiply 2nd eqn by 2 and subtract it from eqn 1st then u will get x then put x in ist eqn then u will get y.
Answer:
I believe it's the first one
4/5 + a = 1
=1/5
*try using cymath it helps!
