For each situation, an inequality is written. Which one has an incorrect inequality?АThree less than a number is greater than negative four and less than negative one; - 4 75DAll real numbers that are greater than or equal to - 7 1/2or less than or equal to zerox < 0 or x>-7 1/2

Respuesta :

Option D has an incorrect inequality.

Since option D Says:

"All real numbers that are greater than or equal to - 7 1/2 or less than or equal to zero"

Greater than or equal is represented with the symbol ≤ or ≥.

So the correct inequality is for this statement is:

x ≤0 or x>-7 1/2

Not

x < 0 or x>-7 1/2

Note that the x and 0 part doesn't have an equal sign.
