you are snow skiing down the 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.
a. After 60 seconds of skiing, you will be 7800 feet high.
b. After 60 seconds of skiing, you will be 5820 feet high.
c. After 60 seconds of skiing, you will be 4200 feet high.
d. After 60 seconds of skiing, you’ll be 6030 feet high.
We can use the linear model y = -30x + 6,000 to find the elevation level after 60 seconds of skiing:
y = -30(60) + 6,000
y = -1800 + 6,000
y = 4,200
Therefore, the correct answer is c. After 60 seconds of skiing, you will be 4,200 feet high.
