Question 156466: 1. Find the equation of the line that has the given characteristics.-Slope (-1/4) passing through the point (5,4)?
2. Find the center and the radius of the circle (x+2)(squared)+y(squared)=9?
3. Is the relation xy=5 a function within the domain (-5,1)?
4. There was a man who was about to take his internet company public. He owned 5% of the 900,000 shares of stock that were issued by the company when the company was first formed. the board of directors decided to reward him by issuing additional stick so that he would then own 10% of the company. How many shares of stock should be issued and then rewarded to him?

When ever I work with percentages, I always divide by 100 to find what 1 percent will equal to. In your problem, 1% of 900,000 is 9,000. The man already owns 5% of the 900,000. to find 5%, multiply 9,000 by 5, which will give you 45,000 shares. the board of directors want him to own 10% of the 900,000. He already owns 5% or 45,000. another 5% will give him 10%, so you are adding 5% to the 5% he already has. 45,000 + 45,000 = 90,000. 90,000 = 10%
Another way to do percentages, particluarly when the numbers are even, is to move the decimal point. For example, 900,000. represents 100% of the shares. Move the decimal point to the left one space - 90,000. - represents 10%. Move the decimal point one more space to the left - 9,000.- represents 1%. But remember, this works best with even or round numbers.
