Step-by-step explanation:
Luci Lulu opened a cookie store in the mall. She found that the relationship between the price of a cookie, p, and the number of cookies sold, x, is given by the linear relationship x = −2000 p + 4000 .
Answers
Answer:
a. The maximum revenue Luci can make selling cookies in one day is $2,000.
b. The price she should sell the cookies for her to make the maximum revenue is $1.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Luci Lulu opened a cookie store in the mall. She found that the relationship between the price of a cookie, p, and the number of cookies sold, x, is given by the linear relationship x = −2000 p + 4000. Find the maximum revenue Luci can make selling cookies in one day. Find the price she should sell the cookies for to make the maximum revenue.
The explanation of the answer is now provided as follows:
Given;
x = −2000p + 4000 …………………………. (1)
The revenue function is obtained as follows:
R = px ……………………….. (2)
Substitute equation (1) into (2), we have:
R = p(−2000p + 4000)
R = −2000p^2 + 4000p ……………… (3)
Obtain the derivative of equation (3), set to zero and solve for p, we have:
−4000p + 4000 = 0
4000 = 4000p
p = 4000 / 4000
p = 1
From the above, p = 1 implies that the price that ensure maximum revenue is $1.
We can now answer as follows:
a. Find the maximum revenue Luci can make selling cookies in one day.
Since p = 1 implies that the price that ensure maximum revenue is $1, we then substitute p = 1 into equation (3) as follows:
R = (−2000 * 1^2) + (4000 * 1)
R = (−2000 * 1) + (4000 * 1)
R = −2000 + 4000
R = 2000
Therefore, the maximum revenue Luci can make selling cookies in one day is $2,000.
b. Find the price she should sell the cookies for to make the maximum revenue.
Since p = 1 implies that the price that ensure maximum revenue is $1 as obtained above, it therefore implies that the price she should sell the cookies for her to make the maximum revenue is $1.

Solve for x over the real numbers:
x^2 - 10 x - 27 = 0
Hint: | Solve the quadratic equation by completing the square.
Add 27 to both sides:
x^2 - 10 x = 27
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 25 to both sides:
x^2 - 10 x + 25 = 52
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 5)^2 = 52
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 5 = 2 sqrt(13) or x - 5 = -2 sqrt(13)
Hint: | Look at the first equation: Solve for x.
Add 5 to both sides:
x = 5 + 2 sqrt(13) or x - 5 = -2 sqrt(13)
Hint: | Look at the second equation: Solve for x.
Add 5 to both sides:
Answer:
x = 5 + 2√(13) or x = 5 - 2√(13)

Required
Order from least to greatest
[tex]7, -3, \frac{1}{2}, -0.8, 0.8, -\frac{1}{10}, -2[/tex]
Convert 1/2 and -1/10 to decimals
[tex]7, -3, 0.5, -0.8, 0.8, -0.1, -2[/tex]
Negative numbers are always the least of all numbers.
In the given list, the negative numbers are:
[tex]-3, -0.8, -0.1, -2[/tex]
The higher the magnitude of a negative number, the smaller it is.
--------------------------------------------------------------------------------------------
Take for instance: -7 and -8.
-8 has a magnitude of 8 and -7 has a magnitude of 7.
Because 8 > 7 (the magnitudes), then
-8 < -7
--------------------------------------------------------------------------------------------
Using the above analysis:
[tex]-3, -0.8, -0.1, -2[/tex] from least to greatest is:
[tex]-3, -2, -0.8, -0.1[/tex]
Considering the positive numbers:
[tex]7, 0.5, 0.8[/tex]
From least to greatest, it is:
[tex]0.5, 0.8, 7[/tex]
Merge the negative and the positive numbers:
[tex]-3, -2, -0.8, -0.1,0.5, 0.8, 7[/tex]
Convert 0.5 and -0.1 back to fractions

Answer:
Please check the explanation.
Step-by-step explanation:
Show that 4x - x² - 7 is always negative.
Given
4x - x² - 7
4x - x² - 7 is always negative because:
-x²-7 will alwas be negative for all the values of x, The value of - x² - 7 will always be less than 4x for all the values of xHence, 4x - x² - 7 is always negative
For example,

write an equation of the line passing through the point (3,2) and is parallel to the line y=\frac{1}{3}x-3
need answer ASAP
Answers
Answer:
Equation of line passing through (3,2) and parallel to line [tex]y = \frac{1}{3}x-3[/tex] is:
[tex]y = \frac{1}{3}x+1[/tex]
Step-by-step explanation:
Given equation of line is:
[tex]y = \frac{1}{3}x-3[/tex]
Slope-intercept form of a line is given by:
[tex]y = mx+b[/tex]
Comparing the given equation of line with general form we get
m = 1/3
Let m1 be the slope of line parallel to given line
Then the equation of line will be:
[tex]y = m_1x+b[/tex]
We know, "Slopes of two parallel lines are equal"
Which means
[tex]m_1 = m\\m_1 = \frac{1}{3}[/tex]
Putting the value of slope
[tex]y = \frac{1}{3}x+b[/tex]
Putting the point (3,2) in the equation
[tex]2 = \frac{1}{3}(3)+b\\2 = 1+b\\b = 2-1\\b = 1[/tex]
Final equation of line is:
[tex]y = \frac{1}{3}x+1[/tex]
Hence,
Equation of line passing through (3,2) and parallel to line [tex]y = \frac{1}{3}x-3[/tex] is:
[tex]y = \frac{1}{3}x+1[/tex]

Answers
Answer:
1. $85
2. $90.10
3.$108.12
4.$54.06
Step-by-step explanation:
100-15=85 (15% of 100 is 15)
6 percent of 85 is 5.10. So 85 + 5.10=90.10
20 percent of 90.10 is 18.02. So add that to the total. 90.10+18.02=108.12
Now divide by 2 to get how much they each will pay 108.12/2 = 54.06

Solve the equation below for x.
0.5(x + 7) + 9 = 43
Answers
Answer:
x = 61
Step-by-step explanation:
0.5(x + 7) + 9 = 43
0.5x + 3.5 + 9.0 = 43
0.5x + 12.5 = 43.0
0.5x = 30.5
x = 30.5 / 0.5
x = 61
The solution to the value of x in the equation is 61
In a mathematical concept, an algebraic expression consists of variables, constants with their arithmetic operations.
From the given parameters
0.5(x + 7) + 9 = 43
Open brackets
0.5x + 3.5 + 9 = 43
0.5x + 12.5 = 43
0.5x = 43 - 12.5
0.5x = 30.5
x = 30.5/0.5
x = 61
