Question 572416: You need at least 4 hours to do your science and history homework. It is 1:00 p.m. on sunday and your friend wants you to go to the movies at 7:00 p.m.
How much time do you have between now and 7:00 p.m. to do your homework?
Let x represent the number of hours spent on science homework and let y represent the number of hours spent on history homework. Write and graph a system of linear inequalities that shows the number of hours you can work on each subject if you go to the movies.

6 hours

And we have because the constraint says "you need at least 4 hours" but you need at most 6 hours if you go to the movies. A graph of the inequality can be accessed here:
