Problema Solution
The equation y=6x+5 estimates the number of U.S. households, in millions, expected to install devices that receive and manage broadband TV and Internet content to the home, where x is the number of years after 2004. For what years will there be at least 23 million homes with these devices? Write your answer as an inequality involving x.
Answer provided by our tutors
since 'y' is expressed in millions, we substitute 'y' with '23' in the equation provided and solve for x:
23>=6x+5
x >= 18/6 = 3
2004+3 = 2007
for years 2007 and beyond there will be at least 23 million homes with such devices (year >= 2007)
