Answer:
We are given the initial price of a car and we are also told that the car sold for a 15% profit which means that the price that the car was sold for is 15% more than it's initial price. This is just a simple multiplication problem which we multiply the initial price by the total percentage plus 0.15
![Sold\ Price = Initial\ Price *(Total\ Percentage+Profit\ Percentage)](https://tex.z-dn.net/?f=Sold%5C%20Price%20%3D%20Initial%5C%20Price%20%2A%28Total%5C%20Percentage%2BProfit%5C%20Percentage%29)
![Sold\ Price = \$5200*(1+0.15)](https://tex.z-dn.net/?f=Sold%5C%20Price%20%3D%20%5C%245200%2A%281%2B0.15%29)
![Sold\ Price = \$5200*(1.15)](https://tex.z-dn.net/?f=Sold%5C%20Price%20%3D%20%5C%245200%2A%281.15%29)
![Sold\ Price = \$5980](https://tex.z-dn.net/?f=Sold%5C%20Price%20%3D%20%5C%245980)
Therefore, our final answer is that the selling price was $5980

Answer:
false
Step-by-step explanation:
Because it multiplying by 2's but 13x2=26 but it says 24 so that why it is false
The slope of a line passing through two points is the ratio between the difference of the y coordinates and the difference of the x coordinates. In formulas, you have
![m(A,B) = \cfrac{\Delta y}{\Delta x} = \cfrac{A_y-B_y}{A_x-B_x}](https://tex.z-dn.net/?f=%20m%28A%2CB%29%20%3D%20%5Ccfrac%7B%5CDelta%20y%7D%7B%5CDelta%20x%7D%20%20%3D%20%5Ccfrac%7BA_y-B_y%7D%7BA_x-B_x%7D%20)
If you plug your values, you have
![m(A,B) = \cfrac{\Delta y}{\Delta x} = \cfrac{-3-9}{2-2} = \cfrac{-12}{0}](https://tex.z-dn.net/?f=%20m%28A%2CB%29%20%3D%20%5Ccfrac%7B%5CDelta%20y%7D%7B%5CDelta%20x%7D%20%3D%20%5Ccfrac%7B-3-9%7D%7B2-2%7D%20%3D%20%5Ccfrac%7B-12%7D%7B0%7D%20)
which is undefined.
In fact, since the two points share the same x coordinate, the segment AB is vertical, and the slope is not defined for vertical lines.
