Answer:
x=4.875
y=-0.25
Step-by-step explanation:
4x – 2y = 10
2x-y=10
y=2x-10
4x + 6y = 18
2x+3(2x-10)=9
8x=39
x=4.875
y=2(4.875)-10
y=-0.25
Enlargement because all sides are being multiplied by 3 times their original amount making if it were a scale factor that were a fraction then it would be a reduction
Answer: 60.5
Step-by-step explanation:
The forecast for the next period using the simple exponential smoothing method is given by:
, where D= actual demand for the recent period,
smoothing factor, F= forecast for the recent period .
