Answer:
6 liters
Step-by-step explanation:
Let x represent the amount of pure concentrate used to make the punch. Then the total amount of concentrate in the punch is ...
0.20·10 +1.00x = 0.50(10+x)
x +2 = 0.5x +5 . . . . . eliminate parentheses
0.5x = 3 . . . . . . . . . . .subtract 2+0.5x
x = 6 . . . . . . . . . . . . . multiply by 2
6 liters of pure concentrate must be added to make a 50% punch.
This is a ceiling function. First points should be empty.
The first point x=-3, f(-3)= -6
The last point x=3, f(3)=0
Answer is bottom, left.
One rule of logs is when you add logs, u can combine the parentheses by multiplying so..
log(10a) + log(100a)
log(10a × 100a). now multiply
