Answer:
(-8 - 4)/(-4 - 0) = -12/-4= 3
y - 4 = 3(x - 0)
y - 4 = 3x - 0
y = 3x + 4
the answer is c
Answer:
79
Step-by-step explanation:
Let's say that N is the number of cards.
So the first step is N+5, because dan bought 5 new cards.
Next his dog ate half the collection, so the 2nd piece of the problem is ![\frac{N+5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BN%2B5%7D%7B2%7D)
The last step is to now make it an equation. Because there are now 46 cards left,
=42.
Now solve for N which is N+5=84=> N=79

Given:
Price of gold in 2001 = (0.5x+300)
Its price tripled in 2008 and then doubled in 2011. In 2016, its price dropped to
of the price in 2011.
To find:
An expression for the price of gold per ounce in 2016.
Solution:
We have,
Price of gold in 2001 ![= (0.5x+300)](https://tex.z-dn.net/?f=%3D%20%280.5x%2B300%29)
Its price tripled in 2008.
Price of gold in 2008 ![= 3(0.5x+300)](https://tex.z-dn.net/?f=%3D%203%280.5x%2B300%29)
Then doubled in 2011.
Price of gold in 2011 ![= 2\times 3(0.5x+300)](https://tex.z-dn.net/?f=%3D%202%5Ctimes%203%280.5x%2B300%29)
In 2016, its price dropped to
of the price in 2011.
Price of gold in 2016 ![=\dfrac{2}{3}\times 2\times 3(0.5x+300)](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B2%7D%7B3%7D%5Ctimes%202%5Ctimes%203%280.5x%2B300%29)
![=2\times 2(0.5x+300)](https://tex.z-dn.net/?f=%3D2%5Ctimes%202%280.5x%2B300%29)
![=4(0.5x+300)](https://tex.z-dn.net/?f=%3D4%280.5x%2B300%29)
![=4(0.5x)+4(300)](https://tex.z-dn.net/?f=%3D4%280.5x%29%2B4%28300%29)
![=2x+1200](https://tex.z-dn.net/?f=%3D2x%2B1200)
Therefore, the required expression for the price of gold per ounce is (2x+1200).
