Answer:
A. 40%
Step-by-step explanation:
Model with an equation
50x = 20
Isolate x
x = 20/50
Simplify
x = 2/5
x = 0.4
Convert the decimal to a percentage (move decimal two places to the left)
0.4 = 40%
Answer:
![f(x) = (x+ 10)(x - 2)](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%28x%2B%2010%29%28x%20-%202%29)
Step-by-step explanation:
We want to rewrite
![f(x) = {x}^{2} + 8x - 20](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%208x%20-%2020)
in the form that would most easily help you identfiy the zeros of the function.
This the same as writing in factored form.
![f(x) = {x}^{2} + 10x - 2x - 20](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%2010x%20-%202x%20-%2020)
Factor by grouping:
![f(x) = {x}(x+ 10)- 2(x + 10)](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%7Bx%7D%28x%2B%2010%29-%202%28x%20%20%2B%2010%29)
Factor further to get:
![f(x) = (x+ 10)(x - 2)](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%28x%2B%2010%29%28x%20-%202%29)
