Answer:
C. 7
Step-by-step explanation:
f(3) means find the f(x) when x =3
Using the chart
f(3) = 7 when x =3
Let p represent the quantity of plates
Let c represent the quantity of cups
Cook 1: 4p + 5c = 25.25
Cook 2: 7p + 3c = 25.50
Use elimination method to solve:
-3(4p + 5c = 25.25) → -12p -15c = -75.75
5(7p + 3c = 25.50) → 35p +15c = 127.50
Add the equations: 23p + 0c = 51.75
Divide by 23 to solve for p: p = 2.25
Answer: the cost of plate is $2.25
The next term is 1.4 larger than the one before it, so the appropriate choice is
_____
However, the description
also correctly describes the relationship between a1 and a2, for example. While this equation is technically correct, it is less useful to work with, so is probably not the expected answer.
Answer:
________
________
<em>now, note that if this was actually subtracting, logically, the answer would be H = 0</em>
<em>however, this is an addition problem, meaning to add a negative and a positive integer to get a negative integer.</em>
