Discuss the below:
1.) Solve and graph.
3x+13 and 3x-20≥-11
2.) Solve and graph.
3x+3≥-18 or 6x + 3≥-9
3.) Solve the system by the elimination method.
5x+2y=-11
7x+3y=19
What is the solution to the system?
(Type an ordered pair. Type an integer or a fraction. Type N if there is no solution. Type I if there are infinitely many solution.)
4.) Graph and write the solution in interval notation.
x<5 and x ≥-2
Write the solution in interval notation.
5.) Graph the inequality on a plane.
4x+5y ≤ 20
6.) Solve. Then graph.
a+6≤-13
7.) Graph the system of inequalities.
x≤2
y ≥-2x+3
8.) Graph system of equations
x+y=3, y =-x+6
x-y=3,y =x+6
Are the equations dependent or independent.
Are they consistent or not consistent.
