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.
To predict your elevation level in feet after 60 seconds of skiing, we need to substitute x = 60 into the linear equation y = -30x + 6,000.
So, y = -30(60) + 6,000.
Calculating this expression, we find:
y = -1800 + 6,000,
y = 4200.
Therefore, your elevation level after 60 seconds of skiing is predicted to be 4,200 feet.
