You are snow skiing down a mountain that is represented by the linear model y =- 30х + 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)

Question

• After 60 seconds of skiing, you will be 7,800 feet high.
• After 60 seconds of skiing, you will be 4,200 feet high.
• After 60 seconds of skiing, you will be 5,820 feet high.
• After 60 seconds of skiing, you will be 6,030 feet high.

Answer 1

To predict your elevation level in feet after skiing for 60 seconds using the linear model \( y = -30x + 6000 \), we can substitute \( x = 60 \) into the equation.

\[ y = -30(60) + 6000 \]

Calculating the expression:

\[ y = -1800 + 6000 \]

\[ y = 4200 \]

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