_____
I like to use a little X-diagram to work mixture problems. The numbers on the left are the contributions made by each constituent. The number in the middle of the X is the target value for the mix. The numbers in the center column are the differences along the diagonals. The numbers in the right column are in the same proportion but scaled to add to the total you need for this problem. (The scale factor is 3.)

Answer:
0.153
Step-by-step explanation:
We have been given that Mafalda has a save percentage of 0.738 so far this hockey season. Last season, her save percentage was 0.585.

Therefore, Mafalda's save percentage improved by 0.153.
Answer:
x + 2y = -8 = y = -4 - 1/2x
y= -1/2x + 4 = y = 4
y= -1/2x - 4 = y = -4
y=-2x - 4 = y = -4
y=1/2x-4 = y = -4
Step-by-step explanation:
(x + 2y = -8 = y = -4 - 1/2x)
