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)
Responses
A After 60 seconds of skiing, you will be 7,800 feet high.
B After 60 seconds of skiing, you will be 4,200 feet high.
After 60 seconds of skiing, you will be 4,200 feet high.
C After 60 seconds of skiing, you will be 5,820 feet high.
D After 60 seconds of skiing, you will be 6,030 feet high.
To find the elevation level after 60 seconds of skiing, you need to substitute x = 60 into the equation y = -30x + 6000.
y = -30(60) + 6000
y = -1800 + 6000
y = 4200
Therefore, after 60 seconds of skiing, you will be 4,200 feet high.
The correct answer is B.
To find the elevation level after 60 seconds of skiing, we can substitute x = 60 into the equation y = -30x + 6,000.
Substituting x = 60, we get:
y = -30(60) + 6,000
= -1,800 + 6,000
= 4,200
So, after 60 seconds of skiing, you will be 4,200 feet high.
Therefore, the correct answer is B: After 60 seconds of skiing, you will be 4,200 feet high.
To determine the elevation level in feet after 60 seconds of skiing, we need to substitute the value of x (60) into the given linear model equation y = -30x + 6,000.
Therefore, we substitute x = 60 into the equation:
y = -30(60) + 6,000
y = -1,800 + 6,000
y = 4,200
So, after 60 seconds of skiing, your elevation level will be 4,200 feet.
Therefore, the correct answer is:
B After 60 seconds of skiing, you will be 4,200 feet high.
