The tallest person who ever lived was approximately 8 feet 11 inches tall.
a. Write an inequality that represents the heights of
every other person who has ever lived.
b. Is 9 feet a solution of the inequality? Explain.

A- W < 8'11"

B- 9 feet is not a solution to the inequality because if the tallest person is 8'11", then no one has ever been taller than that. Therefore, no human has ever been 9 feet which makes 9 feet unneccessary.

Step-by-step explanation:

A- You need a variable to represent the height of every other person who ever lived because there heights ranged from person to person. The inequality is less than because no one has ever been taller than the tallest person ever.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
