For this, all you need is the velocity formula which is Vf = Vi + at.
Vf = final velocity.
Vi = initial velocity.
a = acceleration
t = time
Vf = Vi + at.
Vf= 0 + (-<span> 9.8 m/sec^</span><span>2) (7s)
</span>
*The 0 says that the original velocity is zero. The - 9.8 m/sec^2 is gravity because there is nothing else acting upon it, and it is negative because it is falling. The 7s is time time.*
All you have to do then, is simplify to get 68.6 m/s which is B.

Answer:
Equation:
Step-by-step explanation:
3y = x + 15
y + 3x = 4
To get the y-value Subtract 3x from both sides.
y = -3x + 4
Then substitute;
3(-3x + 4) = x + 15
Distribute: -9x + 12 = x + 15
Subtract x from both sides
-10x + 12 = 15
Subtract 12 from both sides
-10x = 3
Divide both sides by -10
x = 3/-10
Then to get the value of y;
y = -3(3/-10) + 4
