Question

write an inequality for the situation. all real numbers y that are less than 4 or greater than 9 a. 4 < y < 9 b. y ≤ 4 or y ≥ 9 c. y < 9 or y > 4 d. y < 4 or y > 9

Answer 1

All real numbers y that are less than 4: y < 4

All real numbers y that are greater than 9: y > 9

Therefore, y < 4 or y > 9

Answer 2

All real numbers y that are less than 4: y < 4
All real numbers y that are greater than 9: y > 9
Therefore, y < 4 or y > 9
