An airport offers two shuttles that run on different schedules. if both shuttles leave the airport at 4: 00 p. m., at what time will they next leave the airport together? shuttle a leaves every 6min shuttle b leaves every 9 min

4:18 P.M.

Step-by-step explanation:

An airport offers two shuttles that run on different schedules.

Shuttle A leaves every 6 minutes shuttle B leaves every 9 minutes.

If both shuttles leave the airport at 4:00 P.M.

We will calculate the time of next leave the airport together.

First we will calculate Lowest Common Multiple (LCM) of 6 and 9.

Factors of 6 = 1 × 2 × 3

Factors of 9 =  1 × 3 × 3

LCM = 1 × 3 × 2 × 3 = 18

Therefore, after 18 minutes to 4:00 P.M. that is 4:18 P.M. they next leave the airport together.

answer

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
