Given that s varies directly with t, and that s = 4.56 meters when t = 3 seconds, find s when t is 4.2 seconds. note: direct variation means that s is proportional to t.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
