Question 1205777: Brian is studying for his final exams in Chemistry and Algebra. He knows he has less than 22 hours to study, and it will take him at least three times longer to study for Algebra than Chemistry.
Graph the system on your own graph paper with Chemistry as the independent variable and Algebra as the dependent variable. Then, decide which of the four graphs below shows the correct lines (dotted/solid), and then choose the letter for the region on that graph that should be shaded for the solution. If no regions should be shaded, choose No Solution.

Can he spend 14 hours on Chemistry and 9 hours on Algebra?
Can he spend 15 hours on Chemistry and 9 hours on Algebra?
You can put this solution on YOUR website! Taking to mean at least three times as long as for Algebra than for Chemistry
this becomes , a and c, Algebra and Chemistry, .
You can answer the two specific questions at the end simply by substitution and see if the
system is true or false.
