Answer:
the average velocity is 86 km/h for the trip
Step-by-step explanation:
from the definition of average velocity
average velocity = distance covered / time required = 1682 km /(19 h + 28 min/60 min/h) = 86 km/h
therefore the average velocity is 86 km/h for the trip
In year 10, the table says the population is 25,000
But if we plugged x = 10 into the equation Lucy got, then,
y = 600x + 25000
y = 600(10) + 25000
y = 6000 + 25000
y = 31000
Lucy's equation says that the population in year x = 10 should be y = 31000 instead of 25000. So this is one way to show that there is an error. The output from the equation isn't matching what the table shows.

<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the initial value of y.
Let S represent the total cost of service for x months. Given:
y = 35x + 45
This means an initial fee of $45 have to be paid to the provider and a charge of $35 per month.
