Answer:
50 - 15m
Step-by-step explanation:
You start out with 50 dollars so that is the constant.
Each DVD is 15 dollars, so for every dvd(m) it is 15 dollars.
The common difference is 1 1/3
40-1 1/3= 38 2/3
38 2/3-1 1/3=37 1/3
37 1/3-1 1/3=36
Therefore the missing number is 38 2/3

Answer:
Q3: x1=2+i, x2=2-i Q4: x1=-3/2+i, x2=-3/2-i
Step-by-step explanation:
( 
± 
) / 
= (
x1= 2+i
x2= 2-i
( 
± 
) / = (-6 ± 
)/4= (-3 ± i)/2
x1 = -3/2 +i
x2 = -3/2 -i
