Question

A sign at an amusement park reads “To ride, you must be at least 4 1/2 feet tall, but no taller than 6 1/2 feet.” How could you write this as an absolute value inequality, using x as height?≥≤
A. |x+1| ≤5.5
B. |x+5.5| ≤1
C. |x-5.5| ≤ 1
D. |x-1| ≤5.5

Answer 1

A

Answer 2

|x-5.5| ≤ 1
if you have |a|<=b that is -b<=a<=b
so it's C.

Answer 3

A or C?

Answer 4

C for sure

Answer 5

|x-5.5| ≤ 1
-1< x-5.5 <= 1
so we have
4.5<=x<=6.5
i hope it's clear it's C now

Answer 6

Thanks, it was C.

Answer 7

Sorry, you are right :) My bad
