To find the elevation after skiing for 60 seconds using the model \( y = -30x + 6,000 \), we can substitute \( x = 60 \):
\[ y = -30(60) + 6,000 \] \[ y = -1800 + 6,000 \] \[ y = 4,200 \]
So, after 60 seconds of skiing, you will be 4,200 feet high.
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)
