F(6)=2
That is because the 6 in the brackets means x
If f(x) means f(6) x=6
And if you look at the graph where the 6 on the x axis is and look where the graph meets the value of 6 it is on the value of 2 on the y axis
-k-5k=-5k-4
Combine -5k and -k = -6k
-6k=-5k-4
add 5k to -6k which equals -1k
divide -1 by -4
answer k=4
I think the answer might be x=4/8
Let's get the data out of the problem:
d = 38.4 km
t = 6 h
Now, we can apply in this equation and find his speed:
v = d / t
v = 38.4 / 6
v = 6.4 km/h
Joe has a speed of 6.4 km/h.
Hope it helps.
