Answer:
A. 4/5 of a banana
Step-by-step explanation:
Given that a country produces only apples and bananas.
Moving from point A to point B along its production possibilities frontier, 5 apples are gained and 4 bananas are forgone
i.e. preferences for 5 apples are equal to 4 bananas
5 apples = 4 bananas
Let us calculate unit rate i.e. how much 1 apple is equivalent to. this would give the opportunity cost, namely the cost of gain of 1 apple
1 apple= banana
Hence opportunity cost = 4/5
i.e. Option A is right

The correct answer would be (0,2) since in standard form the y-int is C/B
C=-4 & B=-2
C/B = -4/-2 4/2 = 2/1 = 2
y-intercept = 2
It says that you need to divide 2 exponents with the same base, you keep the base and subtract the powers, its kind of like reducing fractions! :)
extraneous root is a solution o an equation that seems to be right but when we check it (by substituting it into the original equation) it turns out not to be right
Step-by-step explanation:
x = -4,
f(4) = -3(-4) + 15
= 12 + 15
= 27
f(0) = -3(0) + 15
= 0 + 15
= 15
f(5) = -3(5) + 1 5
=- 15 + 15
= 0
