9 (x +2) < 3(3-5)
Step-by-step explanation:
9x+18 < 9-15
1)9-15= -6
9x+18 < -6
9x+18= -5

X=2,55556
How much does a book cost?
How many seconds did it take for the object to hit the ground?
How many seconds did it take for the object to reach 1000 feet
Answer:
time = 0 seconds
Time to hit ground = 7.906 seconds
time = 0 seconds
Step-by-step explanation:
t = 0
-16(0)^2 +1000 = 1000
Time for ball to reach ground:
-16t^2 +1000 = 0
-16t^2 = -1000
t^2 = -1000/-16
t = squareRoot (-1000/-16) = 7.906 seconds
