Question

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

Answer 1

-9: NO

3: NO

4: NO

15: YES

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
