Using the equation y = -3x - 1, the missing values are in the ordered pairs, (−3,y) and (x,2), are: x = -1 and y = 8.
How to Compute Missing Values that Satisfies an Equation?An algebraic equation is an expression that has variables. The values of those variables, when plugged into the equation would make the equation true.
Given the equation, y = -3x - 1, substitute x = -3 into the equation to find y:
y = -3(-3) - 1
y = 9 - 1
y = 8
The missing value in the ordered pair is: (-3, 8).
To find the missing value of x in (x, 2), substitute y = 2 into the equation, y = -3x - 1:
2 = -3x - 1
2 + 1 = -3x
3 = -3x
3/-3 = x
x = -1

Step-by-step explanation:
Division A of Aztec Manufacturing purchases materials to be used in production from an outside supplier for $20 per unit. The same materials are produced by Division B. Division B incurs variable costs of $10 per unit. Currently, Division B is able to sell only 320,000 units to outside buyers out of 400,000 units produced. In this situation, if a transfer price of $18 per unit is established between the two divisions and 80,000 units of materials are transferred to Division A, by what amount would Division B's operating income increase? a.$160,000 b.$960,000 c.$640,000 d.$800,000
The operating income of Division B will increase by $640,000
How to calculate the increase in Division B's operating income?
Given that: Division B incurs variable costs of $10 per unit and a transfer price of $18 per unit is established between the two divisions and 80,000 units of materials are transferred to Division A
This cost of production by division B is:
cost = $10 × 80,000 = $800,000
Division B uses a transfer price of $18 per unit. That is:
Selling price = $18 × 80,000 = $1,440,000
Operating income increase = Selling price - cost
Operating income increase = $1,440,000 - $800,000 = $640,000
Therefore, Division B's operating income increase will be $640,000

On October 28, Lee received proceeds of $71,153.66 from the discounted note.
What is note discounting?Discounting a note involves receiving immediate cash by selling it to a financial institution at a discount.
The implication of discounting a note is that the receiver gets less than the maturity value.
The maturity value is the face value of the note plus the computed interest.
Face value of the note receivable = $70,000
Interest rate = 6.34%
Note period = 120 days
July 26 - October 28 = 94 days
Maturity value of the note receivable = The Face Value + Interest
= $71,459.07 [$70,000 + ($70,000 x 6.34% x 120/365)]
Bank discount rate = 6%
The discount period from October 28 to Nov 22 = 26 days (120 - 94)
Bank discount = Maturity Value x Discount Rate x Discount Period
= $305.41 ($71,459.07 x 6% x 26/365)
Proceeds = Maturity value - Bank discount
= $71,153.66 ($71,459.07 - $305.41)
Thus, by discounting the note receivable at LB Bank at 6%, Lee received $71,153.66 instead of the $71,459.07 it would have received at maturity.

Group of answer choices
t=3/(0.05e)
t=ln3/0.05
t=(ln200,000)/0.05
t=log3/0.05
The equation that can be used to find the number of years after 2012 that the population will triple to 300,000 is option B t = ln(3) / 0.05
Given,
The population of a city can be modeled using the formula P=100,000e^(0.05t)
t is the number of years after 2012
P is the population of the city
We have to find the equation that can be used to find the number of years after 2012 that the population will triple to 300,000.
Here,
Substitute 300000 in for P and solve for t
300000=100000e^0.05t
Divide both sides by 100000:
We get,
3 = e^0.05t
Multiply both sides by the natural log (ln)
Then,
ln(3) = 0.05t
Now, divide 0.05 on both sides to get t by its self
t = ln(3) / 0.05
Therefore,
The equation that can be used to find the number of years after 2012 that the population will triple to 300,000 is option B t = ln(3) / 0.05

FIFO LIFO
Ending inventory $10,250 $12,800
Cost of goods sold $17,000 $14,450
How does FIFO differ from LIFO?FIFO, which means First-in, First-out, computes the cost of goods sold based on the assumption that the physical flow of goods sold depends on the earlier inventory in stock.
FIFO can be applied under both the perpetual and periodic inventory systems, unlike LIFO.
LIFO means Last-in, First-out, and as a cost flow assumption assigns the cost of goods sold based on the latest inventory purchases.
LIFO cannot be used under the perpetual inventory system.
