SOLUTION
At the same time t,
Train 1 would have covered a distance of 80t, since distance = average speed x time.
Train 2 would have covered a distance of 70t.
Now both added should give 210 miles
That is 80t + 70t = 210
150t = 210
t = 210/150
t = 1.4 hours
Step-by-step explanation:
4x+y=1-(1)
-6x+y=1-(2)
solve simultaneously
10x =0
X=0/10
X=0
solve for X in (1)
4(0)+y=1
0+y=1
y=1-0
y=1
Answer:
I think it may be B, but double check
<span>This is just notation so we can differentiated between multiple different functions
instead of saying
y=x + 4
we
say
f(x) = x + 4
This is because if we had two functions
y = x + 4
and
y = x - 6
it would get confusing to talk about them, so we use this notation to differentiate between theme easily
by making
f(x) = x + 4
and
g(x) = x - 6
we can now talk about them easily and avoid confusion.
