Properties of numbers 7(x-3)=7x-21

1 answer:

4 0

This property is called the distributive property. It is when you distribute the number outside the parenthesis into the numbers and letters inside the parenthesis.

Example:

7(x-3) = 7x-21

10(x+5+8) = 10x+50+80 = 10x +130

be sure to simplify like terms as in the example above

10 ( x²+5x³+2x²) = 10x²+50x³+20x² = 30x²+50x³

answer: 30x²+50x³

hope this helps

How did speculative investing weaken the stability of the stock market?

tiny-mole [99]

Heavy speculation is a bad idea in any market since it has a tendency to inflate prices to unrealistic levels. That is basically what many investors prior to the Great Depression did when they thought the market would keep going higher and higher. They borrowed money, sold their houses, etc.. to buy into the stock market thanks to that kind of speculation without even considering the underlying reasons for why the market is there in the first place.

lilavasa [31]

Answer:

B. Increasing the production of a good requires larger and larger decreases in the production of another good.

Explanation:

Opportunity cost refers to the foregone units of production of a good in exchange for producing units of another good.

Marginal cost on the other hand refers to additional cost incurred when an additional unit is produced.

Marginal opportunity cost relates to the additional opportunity cost incurred when additional unit of second good is produced in exchange for foregoing or sacrificing units of production of first good.

Increasing marginal opportunity cost would mean as more and more units of good A are produced, for each extra unit of production of Good A, higher units of production of Good B are sacrificed i.e larger and larger decrease in the production of another good.

zimovet [89]

The false statement is both offer an unlimited number of shares in a continuous public offering. (option c)

<h3>What are open-end and closed-end investment companies?</h3>

Open-end investment companies are companies that allow investors invest in their company continuously through the purchase of their shares. On the other hand, closed-end investment companies close their company to new investors

An advantage of open-end investment companies is they are highly liquid. A disadvantage of open-end investment companies is the company is vulnerable from large inflows and outflow of investments.

An advantage of closed-end investment companies is they do not incur charges with regards to the redemption activities of investors. A disadvantage of closed-end investment companies is that investors cannot withdraw their funds until maturity.

Two brothers each open IRAs in 2009 and plan to invest $3,000 per year for the next 30 years. John makes his first deposit on Ja

Goryan [66]

Answer:

Future value of John's investment

FV = A(1+r)n+1 - (1+r)

Fv = $3,000((1 + 0.07)30+1 - (1 +0.07))

0.07

FV = $3,000((1.07)31 - (1.07)

0.07

FV = $3,000 x 101.0730414

FV = $303,219

Future value of Bill's investment

FV = A((1 + r)n - 1)

FV = $3,000 ((1 + 0.07)30 - 1)

0.07

FV = $3,000((1.07)30 - 1)

0.07

FV = $3,000 x 94.46078632

FV = $283,382

The difference in the value of IRAs

= $303,219 - $283,382

= $19,837

The correct answer is A

Explanation:

In the first case, we need to apply future value of annuity due formula since deposits are made at the beginning of each year.

In the second case, we need to apply future value of an ordinary annuity formula since deposits are made at the end of each year.
