Semmy [17]

Answer:

The price of elasticity of demand is 2.59

Step-by-step explanation:

* Lets explain how to solve the problem

- During the past year the price of a laptop computer fell from

$2950 to $2450

- During the same time period consumer sales increased from

430000 to 619000 laptops

- We need to find the price of elasticity of demand

- The rule of price elasticity is:

price elasticity = percentage of change in the quantity ÷

percentage of change in price

* Lets calculate the percentage of change in quantity and the

percentage of chance in price

∵ The percentage of increasing of quantity = (new - old)/old

∵ New = 619000 and old = 430000

∴ The percentage of increasing of quantity =

$\frac{619000-430000}{430000}*100=43.95$ %

∵ The percentage of decreasing of price = (old - new)/old

∵ New = $2450 and old = $2950

∴ The percentage of decreasing of price =

$\frac{2950-2450}{2950}*100=16.95$ %

- Lets substitute these values in the equation above

∴ Price of elasticity of demand = 43.95% ÷ 16.95% = 2.59

* The price of elasticity of demand is 2.59

Which equation is the inverse of y=2x^2-8

shusha [124]

Step-by-step explanation:

In order to get the inverse of equation, we will interchange the variables and solve for x and y as follows.

$y = 2x^{2} - 8$

whereas, $y + 8 = 2x^{2}$

or x = $\sqrt{\frac{y+8}{2}}$

Now, on interchanging the variable we will get the equation as follows.

$x = 2y^{2} - 8$

$x + 8 = 2y^{2}$

y = $\sqrt{\frac{x+8}{2}}$

Two functions are shown below f(x)=8x+10 g(x)=6x-4 What is f(4)-g(3)?

N76 [4]

Answer:

c.28

Step-by-step explanation:

Given

f(x) = 8x + 10 and g(x) = 6x - 4

f(4) = 8*4 + 10

= 32 + 10

= 42

g(3) = 6 * 3 - 4

= 18 - 4

= 14

Now

f(4) - g(3)

= 42 - 14

=28

hope it will help :)
