Answer:
18r - 18
Step-by-step explanation:
-3(-6r+6)
Multiply -3 by -6r = 18r *Negative times a negative equals a positive.
Secondly, multiply -3 times 6 = -18
Combine and check your work.
18r - 18
You said that Y = Mx + B
Subtract B from each side: Y - B = Mx
Divide each side by 'x' : (Y - B) / x = M
Distance descended is denoted by a negative integer,
Initial height =+10 m
Final Depth =−350 m
Total distance to be descended by the elevator =(−350)−(+10)=−360 m
Given, the time is taken by the elevator to descend −6 m=1 minute
Thus, time taken by the elevator to descend −360 m=
(−6)
(−360)
------- [from the formula : speed=
time
distance
]
Answer =60 minutes
