SOLVING LINEAR SOLVING LINEAR INEQUALITIES IN INEQUALITIES IN TWO VARIABLESTWO VARIABLES
Coordinate Plane
Warm-Up1.)Sabina and Lou are reading the same book. Sabina reads 12 pages a day. She had read 36 pages when Lou started the book, and Lou reads at a pace of 15 pages per day. If their reading rates continue, will Sabina and Lou ever be reading the same
page on the same day? Explain.
2.) The drama club is having a car wash as a fundraiser. They wash x cars at $5 each and y trucks at $8 each. They will wash at least 26 cars and 15 trucks. They need to make at least $250. Write 3 inequalities to represent this situation. [One for the
number of trucks, one for the number of cars, and one for the amount they need to make. DON’T forget to define your variables.
3.) Solve: 7b + 3 – 4b = 3 – 3(b +4)
4.) 6(x – 1) = 6x – 1
