Question

A system of inequalities is shown. Which symbol could be written in both circles in order to represent this system algebraically? y 3x x –2 ≤ ≥ < >

Answer 1

"≥"

Explanation:

1) Well, for the sake of clarity we'll use a circle on a number line to represent the point solution of each inequality.

2) Writing the system:

`\left\{\begin{matrix}y\geqslant 3x&\\x\geqslant-2&\end{matrix}\right.`

3) We'll shade the circles and use "≥"
