Answer:
It would be a negative number, no matter what negative integer you put it as.
Step-by-step explanation:
For example, lets substitute -2
f(-2) = -8-4-1 = -13; a negative number
As the three longitudinal lines are parallel:
angle 4 = 5 = 6 = 82 degree (corresponding angles) = 9 = 8 = 7 = 82 degrees (vertical angles)
and
angle 11 = 180-82= 98 degrees (linear pair)
so:
angle 10 = 11 = 12 = 98 degrees (corresponding angles) = 3 = 2 = 1 = 98 degrees (vertical angles)
.
hope you got it
Answer:
72 km/hour
Step-by-step explanation:
20 m/s × (1 km/(1000 m)) × (3600 s/h) = 72 km/h
The rate is 72 kilometers per hour.
