Question

Solve: - 4x + 16 < - 8, $xϵN$. Plot the solution on a number line.

• A. {7, 8, 9 . . . . .}
• B. {6, 7, 8, 9 . . . . .}
• C. {5, 6, 7}
• D. {7, 8, 9}

Answer 1

The correct option is A {7, 8, 9 . . . . .}

- 4x + 16 < - 8., $xϵN$
- 4x < - 24
4x > 24
x > 6
Solution set = {7, 8, 9, 10 . . . . .}
