The equation:
y - y 1 = ( y2 - y1 ) / ( x2- x1) * ( x - x1 )
y - ( - 5 ) = ( 4 + 5 ) / ( - 5 + 7 ) * ( x - ( - 7 ) )
y + 5 = 9/2 ( x + 7 )
y + 5 = 9/2 x + 63 /2 / * 2
2 y + 10 = 9 x + 63
- 9 x + 2 x = 53
Answer:
C ) y + 5 = 9/2 ( x + 7 ) ; - 9 x + 2 y = 53
Step-by-step explanation:
20% of the coins are dimes, and 10 coins are selected, so the expected number of dimes is 0.20 * 10 = 2.
So the number generator is fair. It shows that 20% of the coins selected are dimes most of the time.

Answer:
9n-3
Step-by-step explanation:
Let's set up an expression:
2n-1-(-7n+2)
Now we simplify the expression
2n-1+7n-2
Combine like terms
