A car moving at a constant speed passed a timing device at t=0 . After 7 sec, the car has traveled 644 ft. Write a liner function rule to model the distance on feet d the car has tracked any numbers of seconds t after passing the timing device .

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

you should at least use a calculater

step-by-step explanation:

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
