Answer:
As x increases, y decreases and then increases
Step-by-step explanation:
You need only understand your own description of the graph:
begins above the x-axis, extends below the x-axis, and ascends above the x-axis

Answer:
8 luggage will be left in the compartment that isn't full
How many ounces of nuts are needed to what?
X - speed of the current
40+x - speed with current
40-x - speed against current
t-time
(40+x)*t=100
(40-x)*t=60
40t+xt=100
<span> + 40t-xt = 60
</span> 80t =160
t = 2
40t+xt=100,
40*2+2x=100
80+2x=100
2x=100-80
2x=20
x=10 mi/h
10 mi/h speed of the current.
well since s=8 i the first example and t=16 we know that 2s=t because it says s varies directly. so 16*2=32 t when s=16 is 32
t=32
