we know that
The recipe for 20 chocolate truffles is:
I cup of cream
2 cups of dark chocolate
step 1
Find how many cups of cream are needed for 42 truffles
using proportion
Let
x-----> the number of cups of cream needed
20/1=42/x
x=42/20=2.1 cups of cream
step 2
Find how many cups of dark chocolate are needed for 42 truffles
using proportion
Let
x-----> the number of cups of dark chocolate needed
20/2=42/x
x=42*2/20=4.2 cups of dark chocolate
Answer:f(x)=x2−6x−9 f ( x ) = x 2 - 6 x - 9. Replace f(x) f ( x ) with y y . y=x2−6x−9 y = x 2 - 6 x - 9. Interchange the variables. x=y2−6y−9 x = y 2 - 6 y - 9.
