Answer:
Demand is Elastic when Price > 200 ; Demand is inelastic when Price < 200
Step-by-step explanation:
p = 400 - 4x
4x = 400 - p
x = (400 - p) / 4 → x = 100 - p/4
Elasticity of demand [ P ed ] = (Δx / Δp) x (p / x)
Δx / Δp [Differentiating x w.r.t p] = 0 - 1/4 → = -1/4
P ed = <u>-1</u> x<u> p </u>
4 (400 - p)/4
= <u>-1</u> x <u> 4p </u> = -p / (400-p)
4 (400 - p)
Price Elasticity of demand : only magnitude is considered, negative sign is ignored (due to negative price demand relationship as per law of demand).
So, Ped = p / (400 - p)
Demand is Elastic when P.ed > 1
p / (400-p) > 1
p > 400 - p
p + p > 400 → 2p > 400
p > 400 / 2 → p > 200
Demand is inelastic when P.ed < 1
p / (400-p) < 1
p < 400 - p
p + p < 400 → 2p < 400
p < 400 / 2 → p < 200

-4q = -21
q = 5.25
First blank is 90 degrees and second blank is 2 cause it goes ab then your at c that's 2
Answer:
![Interval: [-10.10]](https://tex.z-dn.net/?f=Interval%3A%20%5B-10.10%5D)
Step-by-step explanation:
Given
Set: -10 to 10
Required
Write as interval notation
We start by writing the given parameter as an inequality
The direct representation of 
and 
in interval representation of sets is 
and ![]](https://tex.z-dn.net/?f=%5D)
, which shows that the beginning and end of the interval are inclusive;
So, the above inequality in interval notation is:
