Question

If x < 5, then which of the following must be true?

Answer 1

Answer choices?

Answer 2

-x < -5
-x > -5
-x < 5
-x > 5

Answer 3

No. it wouldn't be the last one because that would mean that negative x would be greater than 5, but in your case you want something that tells you that 5 is greater..

Answer 4

multiply by -1 and change inequality sign and what do you get ?

Answer 5

I encourage you to graph all four answer choices, plus the given " x < 5 "
Having the graphs to compare should make it easy for you to identify the correct answer.

Answer 6

i don't have graphs

Answer 7

its the 2nd one

Answer 8

correct

Answer 9

When you multiply or divide an inequality by a negative number, the inequality signs changes direction.
You have given: x < 5
Every choice starts with -x, so multiply both sides by -1.

Answer 10

you flip the sign right?

Answer 11

If you divide by a negative, you flip the sign.

I'm afraid you've missed my point. I'm asking YOU to graph each inequality. Graphing inequalities is a basic skill in math.
