The total distance that Dominik will have to walk is the sum of the length of the escalator and the distance that the escalator has traveled. Let t be the time it will take him to reach the top of the escalator. The equation that best models the situation is,
225 ft + (82 ft/min) x t = (106 ft/min) x t
The value of t is 9.375 minutes.
The product of the gift and another sum is 1 (27,18)
8/9 - 1/3 =
8/9 - 3/9 = 5/9
Answer:
y = 2x + 2
Step-by-step explanation:
find slope first
(4-0)/(1- -1) = 4/2
m=2
then use one of the points to solve for b
0 = 2(-1) + b, so b = 2
y = 2x + 2
