- 1What does this mean: a ≤ ba is less than or equal to b
- 2What does this mean: a ≥ ba is greater than or equal to b
- 3What does this mean: a < ba is less than b
- 4What does this mean: a > ba is greater than b
- 5What could the "?" be in this inequality: ? x 2 - 4 = <18It could be any minus number, or a positive number below 11. So basically <11
- 6On a number line, what does a black circle mean?It can be equal to that number
- 7On a number line, what does a white circle mean?It can't be equal to that number
- 8On a number line, what does a white circle with an arrow pointing to the right mean?That the number can't equal whatever number the white circle is on, but could be anything bigger.
- 9What does a black circle with an arrow pointing to the right mean on a number line?That the number could equal the number that the black circle is on or it could be anything higher
- 10On a number line, what does a white circle with an arrow pointing to the left mean?That the number can't equal the number that the white circle is on but it could be anything lower.
- 11On a number line, what does a black circle with an arrow pointing to the left mean?The number could equal the number that the black circle is on and it could also equal anything below it.
- 12What does this mean: -1 < y ≤ 3That y is more than -1 (and can't be equal to -1) and it is less than or equal to 3
- 13On a number line, what does a white circle with a line going to a black circle mean?That the number can't equal the white circle's number, but it could be anything between the white circle and the black circle, and it could equal the black circle
- 14On a number line, what does a white circle with a line going to another white circle mean?That the number can't equal either of the white circles' numbers, but could be anything in between.
- 15On a number line, what does a black circle with a line going to another black circle mean?That the number could equal either of the black circles' numbers and it could equal anything in between.
