Lets solve our system of equations step by step:

equation (1)

equation (2)
Step 1. Replace equation (1) in equation (2)




equation (3)
Step 2. Replace equation (3) in equation (1)



We can conclude that the correct answer is:

Answer:
25 silk leaves
Step-by-step explanation:
The opportunity cost would be what was normally stopped by doing something else, we have two scenarios:
First stage:
A combination of 60 silk roses and 80 silk leaves
Second stage:
A combination of 70 silk roses and 55 silk leaves
Therefore, comparing the two scenarios, by producing more silk roses, the amount of silk leaves is decreased, by the following amount:
80 silk leaves - 55 silk leaves = 25 silk leaves.
Therefore the opportunity cost is 25 silk leaves
Answer:
4
Step-by-step explanation:
Answer:
Step-by-step explanation:
You have a vertex coordinate and 2 points. In order to write the equation for that parabola, you only need the vertex and one point. We will fill in the following work form of the parabola:
, where h and k are from the vertex and x and y are from the point. Filling in:
and
and
and
9 = 9a s0
a = 1.
Now we can write the equation, filling in a, the only unknown we had, which we now know is 1:

|-3|+|7|=10. The distance of the 2 numbers is 10, next multiply 3/5 into 10 and you get 6. -3+6 is 3, so the point you will end up on is 3.
