Answer:
n how many ways can a president, vice president, and a secretary be chosen? It is 12X11X10. Permutation of n things taken r at a time: nPr=n!/(n-r)! 12P3=12*11*10*9!/9!= 12*11*10=1320 ways.
Step-by-step explanation:
8+5+8=21 coins in total.
8/21*7/20=
56/420=
2/15. Hope this helps, and PM me if something's not clear!
Answer:
1) Slope= 2, y-intercept=4, equation: y=2x+4
2.Slope= -10 , y-intercept= 60 , equation: y=-10x+60
Step-by-step explanation:
Slope formula: 
1. Plug in two sets of cordinates into the equation
(0,2) (2,8)
2. Solve, slope =2
3. Plug in one pair into the point slope formula
Point slope formula: 
4. y-8=2(x-2)
5.y-8=2x-4
6. y=2x+4
Do the same for the other equation
