Answer:
x=6
Step-by-step explanation:
h(x) = -( x-2)^2 +16
We want when h(x) = 0
0 = -( x-2)^2 +16
Subtract 16 from each side
-16 = -( x-2)^2 +16-16
-16 = -( x-2)^2
Divide by -1
16= ( x-2)^2
Take the square root of each side
±sqrt(16) = sqrt(( x-2)^2 )
±4 = x-2
Add 2 to each sdie
2 ±4 = x-2+2
2+4 = x 2-4 =x
6 =x -2 =x
since time cannot be negative
x=6
Answer:
A) c + CD = 20
B) 6c + 12CD = 192
Multiplying equation A by -6 we get:
A) -6c -6CD = -120
B) 6c + 12 CD = 192
Adding the equations we get
0 + 6 CD = 72
There are 12 CD's and
c + 12 = 20
There are 8 cassettes
