Answer:
27%
Step-by-step explanation:
15.6 - 11.4 = 4.2
4.2 ÷ 15.6 = .27
.27 = 27%
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:
The slope is 24
Step-by-step explanation:
Use any two points in the graph to find the slope of the graph
- - - - - - - - - - - - - - - - - - - -
Step 1. Use two points
Ex: (10, 320) & (5, 200)
Step 2. Find the slope using the two points
m = slope
m = change in y/change in x
m = (y2 - y1)/(x2 - x1)
m = (200 - 320)/(5 - 10)
m = -120/-5
m = 120/5
m = 24
The slope of the graph/line is 24
Answer:
4 * (3 + 5)
4 * 8
<u>32</u>
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the interval ------> [-1,∞)
-------> inequality B
The solution of the inequality B is the interval ------> (-∞,7]
The solution of the compound inequality is
[-1,∞) ∩ (-∞,7]=[-1,7]
therefore
the answer in the attached figure
