For the pair of supply-and-demand equations, where x represents the quantity demanded in units of 1000 and p is the unit price i
Liono4ka [1.6K]

Answer:

7 and 6 respectively

Step-by-step explanation:

Firstly, we have to solve the equations simultaneously.

2x + 7p = 56

3x - 11p = -45

Multiply equation I by 3 and ii by 2

6x +21p = 168

6x - 22p = -90

Subtract the second from first to yield:

43p = 258

p = 6

Insert this in equation 1 where we have 2x + 7p = 56

2x + 7(6) =56

2x + 42 = 56

2x = 14 and x = 7

The equilibrium price is 6 and the equilibrium quantity is 7

Item 18
nasty-shy [4]

The first thing we have to do is to calculate the midpoint of the min and max speeds. We are given that the min and max is 74 and 95 respectively. The midpoint is then calculated as (max+min) / 2. Therefore:

midpoint = (74 + 95) / 2 = 84.5

 

Next, we calculate the distance from the midpoint to the endpoint by doing subtraction. Therefore:

min endpoint: 84.5 – 74 = 10.5

max endpoint: 95 – 84.5 = 10.5

 

Now we know that v minus the midpoint will equal the distance such that:

| v - midpoint | = distance.

To our problem,

| v – 84.5 | = 10.5

Paladinen [302]

Answer:

x =  \frac{c + d}{b - a}

Step-by-step explanation:

bx-c=ax+d

<=> bx-ax=c+d

<=> (b-a)x=c+d

<=> x=(c+d)/(b-a)
