1.) The price of a personal computer is $2000. The markup is $150. What is the dealer cost?
2.) Solve the inequality 4y - 7 > 9y - 2. Use set-builder notation.
4.) Graph using slope and y-intercept method of 5x + 5y = 10
5.) Graph the inequality 6x + 12y < 18 and shade half-plane solution.
6.) Solve the given system by graphing:
x + y = 7
2x - y = 3
7.) Solve the given system by graphing:
2x + 3y = 6
x + 6y = 12
8.) Solve by addition method:
3x = 5y + 1
4x + 2y = - 3
9.) Solve by addition method:
y = 2x + 1
y = 2x - 3
10.) Graph the solution of system of linear inequalities
y < - 3x + 4
y <= x + 3
The solution shows how to solve the system of linear inequalities and equations via different methods, such as graphing, addition, and substitution.
