Answer:
-27 is the answer of this problem
Answer:
<em>3 seconds</em>
Step-by-step explanation:
Given the height modelled by the function
h(t) = -16t² + 16t + 96
The hit the water at h(t) = 0
0 = -16t² + 16t + 96
Divide through b y -16
0 = t² - t - 6
t² - t - 6 = 0
t² - 3t+2t - 6 = 0
t(t-3)+2(t-3) = 0
t+ 2 = 0 and t - 3 = 0
t = -2 secs and t = 3secs
Since t can't be negative, hence;
t = 3 secs
<em>hence it will take 3 seconds until Devon hit the water</em>
Answer:
If you subtract -2x+y=0 and -7x+3y=2 you will get 5x-2y=-2
Step-by-step explanation:
Subtract -2x and -7x which is 5x
Subtract y and 3y which is -2y
Subtract 0 and 2 which is -2
Result: 5x-2y=-2

Answer:
-17 feet below sea level
Step-by-step explanation:
Garcia is at an elevation of 141 feet, and drops 158 feet. Subtracting 141 from 158 gets 17, therefore the answer is -17. A more straightway option to do this is 141 - 158 which gives you the answer.
