Cost of hosting the tournament : $1,000
If it rains, the club will lose the investment: $ -1,000
If it is sunny, the club will collect $4,500 ; profit: 4,500 - 1000 = 3,500
chance of rain is 20%
-1,000 * 20% = -200
3,500 * 80% = 2,800
2,800 - 200 = 2,600 Choice C.
1. Move the negative sign to the left.
- ![\frac{19}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B8%7D)
*-50
2. Use this rule: ![\frac{a}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D)
![*](https://tex.z-dn.net/?f=%2A)
=![\frac{ac}{bd}](https://tex.z-dn.net/?f=%5Cfrac%7Bac%7D%7Bbd%7D)
-![\frac{19x*-50}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19x%2A-50%7D%7B8%7D)
3. Simplify - ![\frac{-950x}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B-950x%7D%7B8%7D)
4. Move the negative sign to the left.
-(-950x/8)
5. Simplify 950x/8 to 475x/4
6. Remove parentheses.
C. The distance between A and C
Because |-2| = 2
And if you tried all the choices only C gives the same answer
Answer:
1,0
Step-by-step explanation:
No need to expand look at the roots of the brackets.
(x-1)=0
x=1
x^2 and -9x have roots 0
Think of it as whatever sets the expression to 0.
