Apparently you had to scooty out of here before you had a chance to
tell us what the choices are.  So there's no way for anybody to help you
find the correct ones.

For an equation to show direct variation:

-- When either 'x' or 'y' is zero, the other one must be zero too.

-- 'x' and 'y' must both be to the first power in the equation. 
     What I mean is;  no squares or higher powers of 'x' or 'y',
     no square roots, or cubes etc.

and

-- If 'x' or 'y' is in the denominator of a fraction,
then it has to be in the numerator too.

James decides to invest money in Wal-Mart. As a shareholder, he has the advantage of
irakobra [83]

Answer:

A. limited liability

Step-by-step explanation:

Because James has become a shareholder by investing in Walmart, he has the advantage of limited liability. This basically means that he shares in both the gains and the losses of Walmart's business decisions but only up to the amount that he has invested into it. Meaning that if James invested a total of $2000 and Walmart goes under, then he will lose all $2000 but not more than that.

If (6^0)^x= 1 what are the possible outcomes of x? Explain your answer.
swat32
X can be any  real number 

As long as it is to the power of 0, it will equal one. And because 6^0 = 1, 1^x can be any positive number, and it will still give you one.

As stated by WojtekR, even negative numbers can get 1

x = - 5

(6^0)^-5 =  1^-5 = 1/1 = 1

kobusy [5.1K]
To set the equation,we can first find how much price would be raised within a year:

=500×(1+7%)

=500×1.07

As the years go by the increase would accumulate,and the equation would be:

500 \times  {1.07}^{t}
