Question

You are snow skiing down a mountain that is represented by the linear model y=–30x+6,000
, where y
is the number of feet after x
seconds. Predict your elevation level in feet if you ski 60 seconds. (1 point)

After 60 seconds of skiing, you will be 4,200 feet high.

After 60 seconds of skiing, you will be 6,030 feet high.

After 60 seconds of skiing, you will be 5,820 feet high.

After 60 seconds of skiing, you will be 7,800 feet high.

Answer 1

y = -30(60) + 6000 = -1800 + 6000 = 4200 feet.

So: After 60 seconds of skiing, you will be 4,200 feet high.
