Answer:
7.2
Step-by-step explanation:
Since the angle is equal, 24/(x+8.7)=13.1/8.7. x=7.2
The 2X and negative 2X cancel out. Then you add the 3 to the -9 to get -6 they you add the lonely Y to the 5Y so now you have 6Y=-6. Then you divide them both by 6 to get the Y alone. 6Y = 6
— —
6 6
So then it’s Y=1. There you go. Hope I helped!!!

Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
y=-16x^2+129x+119
y=−16x
