X² + 6x - 7 = 0? Um, I usually write that down, but the answer would be x = 7 and x = -1. Since it is set equal to zero, you will have two answers to this equation.
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -7

1 • -7 = -7
-7 + 1 = -6
x2 - 7x + 1x - 7
1 • (x-7)
(x+1) • (x-7)
(x + 1) • (x - 7) = 0
x+1 = 0 therefore x = -1
and
x-7 = 0 therefore x = 7

Although GDP is a reasonably good measure of a nation's output, it does not necessarily include all transactions and production
dezoksy [38]

Explanation:

GDP formula is :  

GDP= Consumption (C)+ Investment (I)+ Government expenditure (G)+ Net exports (exports-imports)  

1.The costs of overfishing and other overly intensive uses of resources  

It is not accounted because GDP only measures the market value of goods and services produced. The cost of overfishing does not fit in any GDP account.  

2. The value of babysitting services, when the babysitter is paid in cash and the transaction isn´t reported

Reported cash services often sum in the consume account but if there is no record it is not accounted in the GDP calculation.

3.  Funds spent by city governments to renovate their buildings

It is accounted in the GDP calculation as a government expense (G)

4. A car that is made in Canada, and sold in the United States

It is accounted because it is consumed in the United States. This should be included in the imports account.

5. The quality of goods available to consumers.  

The quality is measured in some way because prices reveal at some level the good or service quality. But it is not an accurate measure because there are some goods and services which quality is not represented in their price.

The postal service of St. Vincent, an island in the West Indies, obtains a significant portion of its revenues from sales of spe
klemol [59]

Answer:

It is more profitable to maintain the price at $10

Explanation:

Giving the following information:

The souvenir sheets cost the postal service $1.15 each. St. Vincent has been selling these souvenir sheets for $10.00 each and ordinarily sells about 61,000 units. To test the market, the postal service recently priced a new souvenir sheet at $11.00 and sales dropped to 51,000 units.

We need to calculate the actual revenue and decide whether it is more convenient to increase the price or leave it as it is.

Actual revenue= 61,000 units* (10 - 1.15)= $539,850

New revenue= 51,000 units*(11 - 1.15)= $502,350

It is more profitable to maintain the price at $10

Some economists suspect that one of the reasons that economies in developing countries grow so slowly is that they do not have w
kramer

This argument makes sense as some economists suspect that one of the reasons that economies in developing countries grow so slowly is that they don't have well-developed financial markets.

Why do economies in developing countries grow slowly?

The financial market is crucial for facilitating the flow of funds from individuals to investors to promote economic efficiency. It is exceedingly expensive and challenging to establish efficient financial markets in underdeveloped markets in emerging countries, which hurts economic growth.

What causes a country to grow faster than another country?
The labor force in nations having access to new technology and/or a wealth of research and development is frequently more productive than in nations without such access. Economic growth accelerates as productivity rises.
