Step-by-step explanation:
The number of ways to choose a combination of 7 objects from a group of 15 objects is 15! / (7! 8!)
Answer:
y= -5x+15
Step-by-step explanation:
the point-slope formula is
![y-y_{1}=m(x-x_{1} )](https://tex.z-dn.net/?f=y-y_%7B1%7D%3Dm%28x-x_%7B1%7D%20%29)
where m= slope
plug the given point (4,-5) and slope m=-5 into the formula
![y-(-5)=-5(x-4)](https://tex.z-dn.net/?f=y-%28-5%29%3D-5%28x-4%29)
simplify and distribute
![y+5=-5x+20](https://tex.z-dn.net/?f=y%2B5%3D-5x%2B20)
subtract 5 from both sides
![y=-5x+15](https://tex.z-dn.net/?f=y%3D-5x%2B15)
Not enough info. It's unknown what the size of the beads are.
Answer:
1975-76
Step-by-step explanation:
