Answer:
f(x)= 6x+9....
Step-by-step explanation:
The given equation is:
y-6x-9=0
Add 6x+9 at both sides:
y-6x-9+6x+9=0+6x+9
Solve the like terms:
on the L.H.S -6x will be cancelled out by +6x and -9 will be cancelled out by +9
y=6x+9
Now convert it in function notation:
f(x)=y
f(x)= 6x+9....
300, because 8x20=160 so 1 ounces= 20 calories
15x20=300
