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.
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.
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.
If the value is a solution then it will make the statement true when it is substituted in.
10 is grater then 9 so 2 is a solution.
To get a number that makes this false we can solve
