An equation that models the height of an object dropped from the top of a building is y= -16x^2 + 30 where x is time in sec. Another equation, y= 14, models the path of a flying bird in the air. Write a system of equations, and then solve to find how many seconds the object is in the air before it crosses the birds path

1 second

Step-by-step explanation:

The 2 equations are

y = - 16x² + 30 → (1)

y = 14 → (2)

Substitute y = 14 into (1)

14 = - 16x² + 30 ( subtract 30 from both sides )

- 16 = - 16x² ( divide both sides by - 16 )

1 = x² ( take the square root of both sides )

x = = 1

The object is in the air for 1 sec before it crosses the bird's path

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
