The profit earned from postpaid plan subscribers is given by the function P(x) = 0.2x³ - 2000x + 1500, where x represents the number of subscribers and P(x) as the profit. How much is the profit if there are 2000 subscribers?
Answer:
[tex]P(2000) = 1599601500[/tex]
Step-by-step explanation:
Given
[tex]P(x) = 0.2x\³ - 2000x + 1500[/tex]
Required
Find P(x) when x = 2000
To do this, we substitute 2000 for x in [tex]P(x) = 0.2x\³ - 2000x + 1500[/tex]
[tex]P(2000) = 0.2 * 2000^3 - 200 * 2000 + 1500[/tex]
[tex]P(2000) = 0.2 * 8000000000 - 400000 + 1500[/tex]
[tex]P(2000) = 1600000000 - 400000 + 1500[/tex]
[tex]P(2000) = 1599601500[/tex]
Hence, the profit is
[tex]P(2000) = 1599601500[/tex]
4x + 2y = 6
x-y=3
What’s the value of the x variable in this solution?
Hello!
[tex]\large\boxed{x = 2}[/tex]
Solve the system using substitution:
We can rearrange the second equation to find an expression for y:
x - y = 3
Subtract x from both sides:
-y = -x + 3
Multiply the equation by -1:
y = x - 3
Substitute this value of y into the first equation:
4x + 2y = 6
4x + 2(x - 3) = 6
Distribute:
4x + 2(x) + 2(-3) = 6
Simplify and combine like terms:
4x + 2x - 6 = 6
6x = 12
6x / 6 = 12 / 6
x = 2.
Answer:
y = -1
Step-by-step explanation:
x - y = 3
x = 3 + y
4x + 2y = 6
substitute x for 3 + y
4(3+y) + 2y = 6
open the parenthesis
12 + 4y + 2y = 6
12 + 6y = 6
subtract 12 from both sides of the equation
12 - 12 + 6y = 6 - 12
6y = 6 - 12
6y = -6
divide both sides of the equation by 6
6y/6 = -6/6
y = -6/6
y = -1
Select the equation that represents the graph of the line.
A. y= x - 1
B. y - 1/2x - 1

Answer:
12a+200=644
Step-by-step explanation:
take the equation and cancel out 200 and do it to both sides
12a+200=644
-200. -200
------------------------
12a=444
then we need to get the variable alone so divide by 12.
12a = 444
---- ----
12. 12
a=37
444 divided by 12 will equal 37

The scatter plot shows the weight of a child each month.
The birth weight of the child is
kilograms. The child gains an average of per month.
Answer:
The scatter plot shows the weight of a child each month
Step-by-step explanation:
Assuming these are the options from the drop down menu
The scatter plot shows the weight of a child each month.
The birth weight of the child is kilograms
The child gains an average of per month.
x-axis shows the age of the baby in months and the y-axis shows the weight of the baby in kilograms. So lets take the first point (1 , 4) which means a baby of 1 month weighs a total of 4 kilograms
The scatter plot represent the weight of a child each month and the same should be considered.
Weightage of the child:Here x-axis represent the age of the baby in months and y-axis represent the weight of the baby in kilograms.
So here the first point be like (1,4) that means the baby of 1 month weighted the total of 4 kilograms.
hence, The scatter plot represent the weight of a child each month and the same should be considered.

If triangle ABC is rotated 180 degrees, reflected over the y-axis, and reflected over the X-axis, where will point A' lie?
O (5, -4)
O(4,-5)
O(-4,5)
O-5,4)
Point A lies on (5, -4).
Given that,
If triangle ABC is rotated 180 degrees, reflected over the y-axis, and reflected over the X-axis,
We have to determine,
Where will point A lie?
According to the question,
When rotating a figure of 180 degrees about the origin either in the clockwise or counterclockwise direction, each point of the given figure has to be changed from (x, y) to (-x, -y) and graph the rotated figure.
Then, the points after rotation are (-5, -4).
When the reflection about the y-axis, (5,4) becomes (-5, 4).
Reflect again about the x-axis, (-5, 4) becomes (5,-4).
Hence, point A lies on (5, -4).

The number of traffic violations in a city increased from 12 to 16 in a month. What is the percent of increase in the number of traffic violations for that month? Round to the nearest percent, if necessary.
Answer:
33%
Step-by-step explanation:
Percentage increase = [tex]\frac{increase}{initial value}[/tex] x 100%
Number of traffic violations increased from 12 to 16.
Initial value = 12
Final value = 16
increase = Final value - Initial value
= 16 - 12
= 4
Percentage increase = [tex]\frac{increase}{initial value}[/tex] x 100%
= [tex]\frac{4}{12}[/tex] x 100%
= [tex]\frac{1}{3}[/tex] x 100%
= [tex]\frac{100}{3}[/tex]%
= 33.3333%
The percentage increase in the number of traffic violations for the month is 33%.
