Question

Which of the following is not a way to represent the solution of the inequality 2x + 1 >= 19?

x >= 9

9 <= x

A number line with a closed circle on 9 and shading to the right.

A number line with a closed circle on 9 and shading to the left.

Answer 1

Which one do you think?

Answer 2

9 <= x

Answer 3

9<=x is the same as x>=9

Answer 4

The > points to the x in both sentences

Answer 5

but ones less and ones greater?

Answer 6

9<=x says that 9 is less than or equal to x. That means that x is greater than or equal to 9.

Answer 7

In other words you can read the sentence from left to right or from right to left.

Answer 8

so its not what i thought obviously *face palm*

Answer 9

I guess. I don't know what "face palm" is.

Answer 10

face palm means i was stupid so i cover my face with my palm.

Answer 11

So did you solve it?

Answer 12

no not yet. i left it blank.

Answer 13

I think its the closed circle shading to the right.

Answer 14

x>=9 says that x is greater than or equal to 9
9<=x says that x is greater than or equal to 9
If you put a closed circle on 9 and make a line to the right you are indicating the numbers that are greater then or equal to 9

So those three all say the same thing. Do you see that?
