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
Answer:
60 square units; 40 units
Step-by-step explanation:
to find the missing side you use the pythagorean theorem
a^2 + b^2 = c^2
8^2 + b^2 = 17^2
64 + b^2 = 289
b^2 = 225
b = 15
area is l*h*1/2
15 * 8 * 1/2 = 60 square units
perimeter is adding them all
15 + 8 + 17 = 40 units
Answer:
The Graph having the X-intercepts of (-2,0) and (4,0)
Step-by-step explanation:
The zeroes of the function is the X-intercept.
Answer:
nth term is;
0.5n-0.5
Step-by-step explanation:
As we can see, the first term is 0
The common difference is 0.5-0= 1-0.5 = 1.5-1 = 0.5
Formula for nth term of an arithmetic sequence is;
a + (n-1)d
So we have
0 + (n-1) 0.5
= 0.5n-0.5
