3x + 4 > 9, with x = 2
determine whether or not the solution provided is a solution to the inequality. If the value he or she provides is a solution, provide a value that is not a solution. If the value is not a solution, provide a value that is a solution.

  • algebra -

    3x+4>9
    3(2)+4>9
    6+4>9
    10>9

    The value x=2 is a solution to the inequality. A value of x that would not be a solution would be any value lesser than 2, such as 1,0, or -1.

  • algebra -

    3x + 4 > 9,

    Solve the inequality
    3x + 4 > 9
    3x > 5
    x > 5/3 = 1.67

    Therefore, for x to be a solution,
    x > 1.67

    You should be able to finish the problem from here.

  • algebra -

    If the value is a solution then it will make the statement true when it is substituted in.
    3*2+4=10
    10 is grater then 9 so 2 is a solution.
    To get a number that makes this false we can solve
    3x+4=9.
    X=5/3
