Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)
 -4/3 = (6 - y)/[4-(-2)]
 -4/3 = (6-y)/6
 (-4/3)×6 = 6-y
 -8 = 6-y
 y = 6 + 8
 = 14
 
        
                    
             
        
        
        
Answer:
y=4x-1
Step-by-step explanation:
4x-y=1
4x=y+1 then negative Y becomes positive after going to the other side of the equal sign.
4x-1=y the positive 1 becomes negative after going to the other side of the equal sign.
 
        
                    
             
        
        
        
Area of circle = pi r^, (r)radius is half the diameter so 9÷2=4.5 so in this scenario it would be 3.14×4.5^
3.14×4.5×4.5=63.6
circumference of circle= diameter×pi (3.14) 
so 9×3.14=28.3

Answer:
Velocity of the 24.6 g marble is 31 cm/s.
Step-by-step explanation:
Given:
Marble 1:
Mass of the marble  = 12.3 gm
 = 12.3 gm
Velocity of  before collision
 before collision  = 15.5 cm/s
 = 15.5 cm/s
Velocity of  after collision
 after collision  = 77.5 cm/s
 = 77.5 cm/s
Marble 2: 
Mass of the marble  = 24.6 gm
 = 24.6 gm
Velocity of  before collision
 before collision  = 62 cm/s
 = 62 cm/s
Velocity of  after collision
 after collision  = ?
 = ?
From the law of conservation of momentum, we know that momentum before equals the momentum after :
So,
⇒ 
⇒  
 
⇒ Plugging the values.
⇒ 
⇒ 
⇒ 
⇒  ...subtracting both sides 953.25
 ...subtracting both sides 953.25
⇒ 
⇒  ...dividing both sides with 24.6
 ...dividing both sides with 24.6
⇒ 
⇒  cm/s
 cm/s
The velocity of the 24.6 g marble after the collision is 31 cm/s and it will move opposite to of the 12.3 g marbles that is towards left.
