Answer:

x=-3

Step-by-step explanation:

1-7x-7=15

We move all terms to the left:

1-7x-7-(15)=0

We add all the numbers together, and all the variables

-7x-21=0

We move all terms containing x to the left, all other terms to the right

-7x=21

x=21/-7

x=-3

nordsb [41]

Answer:

initial velocity = 64 m/s

Step-by-step explanation:

Differentiate H = 64t - 16t² to find an equation for velocity:

Velocity = \frac{dH}{dt} = 64 - 32t

Initial velocity (u) is when t = 0:

   u = 64 - 32(0)

⇒ u = 64 - 0

⇒ u = 64 m/s
