Answer:p = (2100 - x)/25
Step-by-step explanation:
According to the law of demand, when the price,p of the brand of MP3 players is is high, the quantity,x of the brand of MP3 players demanded would be low and when the price,p of the brand of MP3 players is is low, the quantity,x of the brand of MP3 players demanded would be high.
To derive the demand equation, we would apply the slope intercept form of equation which is expressed as
y = mx + c
Where
m = slope
c = intercept
The slope, m would be
(y2 - y1)/(x2 - x1)
Slope = (1100 - 100)/(40 - 80) = 1000/-40
Slope = - 25
To find the y intercept, we would substitute m = - 25, y = 1100 and x = 40 into y = mx + c. It becomes
1100 = - 25 × 40 + c
1100 = - 1000 + c
c = 1100 + 1000 = 2100
y = - 25x + 2100
Therefore, the demand equation is
x = - 25p + 2100
25p = 2100 - x
p = (2100 - x)/25
It equals 1.7 because you're moving the decimal point by two places, when dividing by 100
So i got 90 4/7 reduced in fractions
Answer:
There can be a number of correct answers. One of them is the ship has traveled 25 miles in 1 hour.
Step-by-step explanation:
The distance from destination f after x hours for the ship is given by f(x)=120-25x
At the beginning, x=0, f(x)=f(0)=120
After 1 hour, f(x)=f(1)=120-25=95
So in 1 hour, the ship has traveled 120-95=25 miles.
