Answer: -4x-34y-32

(I think this is right but I am not completely sure... if its not I am sorry :/ )

Step-by-step explanation:

First Way:

48 (1/4x - 1/3y - 2/6x - 3/8y - 2/3)

48[(6/24x-8/24x)-(8/24y+9/24y)-2/3]

48(-2/24x-17/24y-2/3)

48(-1/12x-17/24y-2/3)

-4x-34y-32

Second Way:

48 (1/4x - 1/3y - 2/6x - 3/8y - 2/3)

12x-16y-16x-18y-32

-4x-34y-32

An object is launched from a platform. Its height (in meters) , x seconds after the launch, is modeled by h(x) = -5(x+1)(x-9)
valkas [14]
Because the time right at launch equals 0 (0 seconds have passed since the launch) solve the equation for 0.
-5(0 + 1)(0 - 9)
-5(1)(-9)
-5(-9)
45
The object was 45 metres above the ground at the time of the launch.
