Answer: A) 3(10 - 5y) + 6y =12
Step-by-step explanation:
As per the question , the given system of linear equation :

Here , To solve the system of equations using substitution , Johanna isolates x in the second equation and writes

As per the substitution method , the next step is to substitute the isolated value of 'x' in first equation , thus the next step will become

Hence, the correct option is A) 3(10 - 5y) + 6y =12

Answer: The rocket will reach its max after 4 seconds
Step-by-step explanation:
Hi, to find the maximum height, we have to set the first derivative of the equation equal to zero.
y=-16x^2+128x+136
0 = (2)-16x +128
0= -32x+128
Solving for x:
32x = 128
x = 128/32
x = 4 seconds
The rocket will reach its max after 4 seconds
