Answer:
- 0 < x < 4
- (- ∞ < x < 0) ∪ (4 < x < ∞)
- x ∈ {0, 4}
Step-by-step explanation:
1. The solution is the set of x-values for which the graph is above the x-axis, where y = 0. Those x-values are in the interval (0, 4).
__
2. The solution is the set of x-values for which the graph is below the x-axis. Those x-values are in either of the two intervals (-∞, 0) or (4, ∞).
__
3. The x-intercepts of the graph are x=0 or x=4.
Answer:k equals 4.5
Step-by-step explanation: you multiply 1.5 times three
First step=
we need to find time for i mile
which is
75/3000=1/40
then to find for 4000 miles we multiply that by 4000
which is 1/40x4000
cancel zeros
1/4x400
=100 hours for 4000 miles
