Answer:
(-5,1)
Step-by-step explanation:
Find the slope of the line connecting (1990,435000) and (2005,482300):
482300-435000 47300
m = ----------------------- = ---------------- = 3153/yr (approx)
2005 - 1990 15 yr
Use the point-slope formula to find the equation of this str. line:
y-435000 = (3153/yr)(x-1990)
The year 2020 is 30 years after 1990. Thus, the expected pop in 2020 is
given by y-435000 = 3153(30) = 94590, so that y = 529590.

Answer:
speed = distance / time
At 96miles in 2 hours
the speed = 96miles/ 2hours = 48miles per hour
at 5 hours, Distance = speed x time
distance = 48 x 5 = 240miles
Step-by-step explanation:
step 1 : determine the speed per hour
speed = distance / time
step 2 : after getting the speed of the car per hour, the distance cover in 5hours can now be determine using
distance = speed x time
