determine whether the given numbers are solutions of the inequality x-3>7;-9,3,4,15

ANSWER:
-9: NO
3: NO
4: NO
15: YES
STEP-BY-STEP EXPLANATION:
We have the following inequality:
[tex]x-3\ge7[/tex]We solve for x:
[tex]\begin{gathered} x-3+3\ge7+3 \\ x\ge10 \end{gathered}[/tex]Which means that the solution is all numbers equal to or greater than 10.
Therefore:
Which means that -9, 3 and 4 are not solutions of the inequality.
15 if it is a solution it is of the inequality
