X + Y = 10
X + 2Y = 16
First, subtract Y from both sides in X + Y = 10.
X = 10 - Y
X + 2Y = 16
Next, plug X into X + 2Y = 16.
X = 10 - Y
10 - Y + 2Y = 16
Afterwards, simplify.
X = 10 - Y
Y + 10 = 16
Subtract 10 from both sides in Y + 10 = 16
X = 10 - Y
Y = 6
Finally, plug Y into X = 10 - Y
X = 10 - 6
Y = 6
Simplify
X = 4
Y = 6

Using the function 2*1/2^3t given, it is just to input the value given to the function.
Or in other words, replace the letter, with the number.
Like this
F(2) = 2*1/2^3*2
F(2) = 2*1/2^6
F(2) = 2*1/64
F(2) = 2/64 = 1/32
1/32 is the answer.
If your formatting was correct. :)
So first you need to factor and get 8( t-1 ) (2t+1)=0. Then you need to divide both sides by 8 to isolate the equation. 0/8=0 so ( t-1 ) (2t+1)=0. Next set each of the factors = to 0 and get t-1=0 and 2t+1=0. Solve, and get t=1 and t=-1/2. The negative does not apply so you know it takes 1 second for the ball to hit the ground.
