    1.) Solve and graph.
    3x+13
    The solution is {x|x ____}

    2.) Solve and graph.
    3x+3 or 6x + 3
    The solution is {x|x _____}

    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
    Write the solution in interval notation.

    5.) Graph the inequality on a plane.
    4x+5y

    6.) Solve. Then graph.
    a+6
    The solution is {a|a ________}.

    7.) Graph the system of inequalities.

    x
    y

    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.

    Hi, Please find the explanations/solutions attached herewith.

    1.) Solve and graph.
    3x+13
    The solution is {x|x ____}

    Solution:

    3x + 13 ≥ 4
     3x ≥ 4- 13
     3x ≥ - 9
     x ≥ -3

    and

    3x - 20 ≥ -11
    3x ≥ -11 + 20
    3x ≥ 9
    x≥ 3

    The solution will be {x|x≥ 3}

    2.) Solve and graph.
    3x+3 or 6x + 3
    The solution is {x|x _____}

    Solution:

    3x+3
     3x - 3
     3x
     x

    OR

    6x + 3
    6x
    x

    The solution is {x|x -7}

    ...
