Answer:
a. D'(p) = -10p - 6
b. There is a decrease of 96 units of demand for each dollar increase
Step-by-step explanation:
The demand function is:

(a) The derivate of the demand function with respect to price gives us the rate of change of demand:

(b) When p = $9, the rate of change of demand is:

This means that, when p = $9, there is a decrease of 96 units of demand for each dollar increase.
Let X be chickens
Let Y be pigs,
then x+y=13
the animals have 2x+4y legs,
so 2x+4y=40
The system of the equations
[X+y=13
[2x+4y=40
Divide the second equation by 2
[x+y=13
[x+2y=20
subtract the first equation from the second one
y=20-13
y-7 pigs
substitute y=7 into the first equation
x+7=13
x=13-7
x=6 chickens
1.true
2.true
3.because it supposed to be 4 sides like a rhombus
I’m not sure if they are right
The answer is: 0.69 EUR : 15 MEX ; or 0.046 (EUR: MEX) .
____________________________________________________
Note: 0.69 EUR: 15 MEX = 0.69 EUR / 15 MEX =
(0.69 ÷ 15) EUR: MEX
= 0.046 EUR: MEX
