Answer:
Final alloy
- weighs
grams - contains
grams of cooper - percent of cooper in alloy is
![43.4375\%](https://tex.z-dn.net/?f=43.4375%5C%25)
Step-by-step explanation:
Suppose that a certain alloy is made by mixing 90 grams of an alloy containing 50% of copper with 70 grams of an alloy containing 35% copper.
50% alloy contains
grams of cooper
35% alloy contains
grams of cooper
Final alloy
- weight
grams - contains cooper
grams - percent of cooper in alloy
![=\dfrac{69.5}{160}\cdot 100\%=43.4375\%](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B69.5%7D%7B160%7D%5Ccdot%20100%5C%25%3D43.4375%5C%25)
The vertex of the absolute value function f(x) = |x| is (0,0).
What about <span>f(x)=-|x+2|-2? This can be re-written as f(x) = -|x-(-2)| -2.
Three things happen here: first, the graph of f(x) = |x| must be inverted, so that it opens down instead of up; second, the resulting graph must be translated 2 units to the left; and third, the resulting graph must be translated 2 units down.
