Answer:
infinite solutions
Step-by-step explanation:
-3f + 3f = 0
0=0
This is always true so there are infinite solutions
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.
The slope m is found from the following formula:

The correct choice is -14.
Step-by-step explanation:
0.001374
standard form means writing a value in shortened form, because sometimes values are too big or small to be written, so we use standard form.
in standard for the decimal always comes after the first digit
so,

the decimal moves 3 digits to the right so it becomes ten raised to the power minus 3.
