Answer:
A x=5 y=-2
Step-by-step explanation:
y = x − 7 ; 3 x + 7 y = 1
y = x - 7
Substitute
x − 7 for y in 3 x + 7y = 1:
3x + 7y = 1
3x + 7(x-7) = 1
10x - 49 = 1
10x = 50
x = 5
Substitute:
y = 5 - 7
y = -2
It will take the roller coaster 171.652 seconds to pass over the hill and reach ground level
<h3>How to determine the time to hit the ground?</h3>
The function is given as:
h = –.025t^2 + 4t + 50
Set h = 0.
So, we have:
–.025t^2 + 4t + 50 = 0
Using a graphing calculator, we have:
t = -11.652 and t = 171.652
Time cannot be negative.
So, we have:
t = 171.652
Hence, it will take the roller coaster 171.652 seconds to pass over the hill and reach ground level
