Answer:
2/3
Step-by-step explanation:
Less than 5 is 1,2,3,4 and 4 out of 6 is also equal to 2/3
You haven't supplied the "output value."
Supposing that the "output value" were 15, then F(x) = x + 7 = 15, and x = 8.
Given:
1st recipe
y = 16x + 560
where x is the number of teaspoons of sugar ; y is the total number of calories
2nd recipe
tsps of honey 1 2 4 7
total calories 504 568 696 888
There are 16 calories in a teaspoon of sugar.
There are 64 calories in a teaspoon of honey.
568-504 / 2 - 1 = 64/1
696-568 / 4 - 2 = 128/2 = 64
888-696 / 7 - 4 = 192/3 = 64
The answer is D! I hope this helps..
