Question

Which of the following sets would have a graph with an open circle on 5 and a ray pointing left on the number line?. 1) x . 2) x R, x > 5. 3) x R, x < 5

Answer 1

3) x R, x < 5

Step-by-step explanation:

An open circle shows that the number is not included .A ray pointing left on number line denotes less than that is < sign.

Among all the options option 3 gives us the the right option that is x belongs to set of real numbers such that x<5. x R, x < 5

Answer 2

The correct answer is choice 3, x.

Step-by-step explanation:
Since the circle on 5 is open, this means it must be strictly less than or strictly greater than; 5 is not itself included in the solution so there can be no "or equal to" part of the symbol. Since the ray points to the left, that is the numbers less than 5, so we must have x<5.
