Answer:
4 sec
Step-by-step explanation:
let y = 0 which is the height when the rocket hits the ground
-3t^2 + 6t + 24 = 0
-3(t^2 - 2t - 8) = 0
-3(t - 4)(t + 2) = 0
t = 4 or t = -2
time cannot be negative, so t = 4 sec
Heya user
we have
7x - 6y and x + y
according to the question
( 7x - 6y ) + ( x + y )
→ 7x - 6 y +x + y
→ 8x - 5y
Hope This helps you
increase in x results in the decrease in y
