Answer:
x = 1.8
Step-by-step explanation:
2 ( 4x-3) - 8 = 4-2x
Distribute
8x -6 -8 = 4- 2x
Combine like terms
8x - 14 = 4 - 2x
Add 2x to each side
8x - 14 +2x = 4-2x+2x
10x-14 = 4
Add 14 to each side
10x-14+14 = 4+14
10x = 18
Divide by 10
10x/10 = 18/10
x = 1.8
Answer: what are you talking about????????
Step-by-step explanation:
Answer:
Assuming "the speaker takes up 1/6 of the internal volume"
volume is 9³ in³
you want the remaining volume, which is 5/6 of the total
(5/6)9³ = 607.5 in³
double that if you want the remaining volume for BOTH speakers....
Answer:
$48 per unit
Step-by-step explanation:
Increasing the price by $5 reduces demand by 20 units, so the slope of the curve is -4 units per dollar. This lets us write a demand equation as ...
q = -4(p -50) +184
q = -4p + 384
q = 4(96 -p)
The revenue is the product of price and demand:
r = pq = 4p(96 -p)
This is the equation of a quadratic curve that opens downward and has zeros at p=0 and p=96. The vertex (maximum) will be halfway between the zeros, at ...
p = (0+96)/2 = 48
A price of $48 per unit will yield a maximum total revenue.
