Question

Write an inequality for the situation. all real numbers y that are less than 4 or greater than 9

Answer 1

The Correct answer would be C... A would only be correct if they said equal to or less/greater than.

Answer 2

Answer: Hello mate!

The notation:

a < b

means that the number b is bigger than the number a, and the notation:

a ≤ b  

means that the number b is bigger or equal than the number a.

"all real numbers y that are less than 4"

this is written as:

y < 4

"all real numbers that are greater than 9"

this is written as:

y > 9

then, the situation can be written as:

y <4 and y >9, which means that the right answer is option C.
