We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0 
                                                              y^2-3y=0
                                                             y(y-3)=0
                                                               y1=0 -----------y2=3

The value of ending inventory will be items of latest purchase.

Step-by-step explanation:

Given that,

Lisa Company uses the periodic inventory system to account for inventories.

Information related to Lisa Company's inventory at October 31 is given,

Suppose, find the value of ending inventory using the FIFO cost assumption if 500 units remains on hand at october 31

We need to calculate the value of ending inventory

Using FIFO method

value\ of\ ending\ inventory =305\ units\times\$10.6+195\ units\times\$11.60

value\ of\ ending\ inventory = 3233+2262

value\ of\ ending\ inventory =\$5495

Hence, The value of ending inventory will be items of latest purchase.

alexira [117]

Answer:

90°

Step-by-step explanation:

180-124=56 so angle a is 56 and a=c so c would also be 56 next you'd have to add the right angle with angle c. 90+56=146 then to get the angle for b you would have to subtract 180-146 which is 34

34+56=90°

. IF F(x) = 2(x-3) + 4, what is F(-2)?
Virty [35]
F(x) = 2(x-3) + 4
F(-2) = 2(-2-3) + 4
F(-2) = 2(-5) + 4
F(-2) = -10 + 4
F(-2) = -6

Hope this helps
