Answer:
The exponential smoothing forecast for period 13 = 39.68
Step-by-step explanation:
As given,
= 0.4
Time Sales forcast
1 48
2 41 48
3 37 48 + = 45.2
4 32 45.2 + = 41.92
5 36 41.92 + = 37.95
6 31 37.95 + = 37.17
7 43 37.17 + = 34.70
8 52 34.70 + = 38.02
9 60 38.02 + = 43.61
10 48 43.61 + = 50.17
11 41.9 50.17 + = 49.30
12 29.7 49.30 + = 46.34
13 46.34 + = 39.68
∴ we get
The exponential smoothing forecast for period 13 = 39.68

Answer:
x=-60
Step-by-step explanation:
convert to x over -6 =10
multiply both side by -6, write as x(-6) over -6= 10(-6)
simplify making x=-60
The answer would be 11 because the x's 9 doesnt have to move because they're on the same point. If you take 7 away from -7 you get zero. Add 4 to that 7 and you get 11. Make sesnse? Hope this helped!

Answer:
the greatest common factor would be 14 . Hope this helped
Step-by-step explanation:
4x + 9 = 68
Subtract 9 from both sides:
4x = 59
Divide both sides by 4
X = 59/4
X = 14.75
