Question

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

Answer 1

ANSWER:

-9: NO

3: NO

4: NO

15: YES

STEP-BY-STEP EXPLANATION:

We have the following inequality:

$x-3\ge7$

We solve for x:

$\begin{gathered} x-3+3\ge7+3 \\ x\ge10 \end{gathered}$

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
