The set of real numbers greater than or equal to -2, but less than 10

Answer 1

So on one end, we have a variable set being greater than or equal to -2:

x ≥ -2

or flipped, -2 ≤ x (you'll see why in a minute)

On the other end, we have x less than 10:

x < 10

That gives us the following:

-2 ≤ x, x < 10

Then we can sandwich the x into the following:

-2 ≤ x < 10
