Paula drops a pebble into the ocean from a 120ft high cliff. Use the formula t=h‾√4 to find how many seconds it takes for the pebble to reach the ocean. Round your answer to the nearest tenth of a second.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
