The cost that will maximize the demand, considering the quadratic function, is given as follows:
$3.
How to maximize the demand?The quadratic function representing the demand is given as follows:
y = -10x² + 60x + 180.
The vertex of a quadratic function is the point on the graph where the function reaches its maximum or minimum value. For a quadratic function in standard form y = ax² + bx + c, the x-coordinate of the vertex is given by:
x = -b / (2a)
The coefficients of the quadratic function in this problem are given as follows:
a = -10, b = 60.
The x-coordinate is the price that maximizes the demand, hence it is obtained as follows:
x = -60/(2 x (-20))
x = 3.

A steak costs $4 more than a hamburger, and a hamburger costs $4 more than a grilled cheese sandwich. If six grilled chees sandwiches cost 2x dollars, how much will 4 steaks and 2 hamburgers cost?
(I understood this question but I don't know why I am keep getting the wrong answer lol)
Answers
Answer:
6(x/3)+ 40= 2x+ 40.
Step-by-step explanation:
Let "C" be the cost of a grilled cheese sandwich.
"A hamburger costs 4 more than a grilled cheese sandwich" so a hamburger costs C+ 4.
"A steak costs 4 more than a hamburger" so a steak cost (C+ 4)+ 4= C+ 8.
"If 6 grilled cheese sandwiches cost 2x dollars" then 6C= 2x so C= 2x/6= x/3.
"how much will 4 steaks and 2 hamburgers cost?"
One steak cost C+ 8 so 4 steaks cost 4(C+ 8)= 4C+ 32. One hamburger cost C+ 4 so 2 hamburgers cost 2(C+ 4)= 2C+ 8. Together that would be 4C+ 32+ 2C+ 8= 6C+ 40.
Since C= x/3, 4 steaks and 2 hamburgers cost 6(x/3)+ 40= 2x+ 40.

Write the prime factorization of 1008 and 1323. Then
reduce 1008/1323
Answers
Answer:
The prime factorization of 1008 is:
1008 = 2^4 × 3^2 × 7
The prime factorization of 1323 is:
1323 = 3 × 19 × 23
To reduce 1008/1323, we need to simplify the fraction by dividing the numerator and denominator by their greatest common factor (GCF). To find the GCF of 1008 and 1323, we can use their prime factorizations. The only common prime factor they share is 3, so the GCF is 3.
1008/1323 = (3 × 336)/(3 × 441) = 336/441
We can simplify this fraction further by dividing both the numerator and denominator by 7, which is the GCF of 336 and 441.
336/441 = (7 × 48)/(7 × 63) = 48/63
Finally, we can simplify this fraction by dividing both the numerator and denominator by their GCF, which is 3.
48/63 = (3 × 16)/(3 × 21) = 16/21
Therefore, 1008/1323 simplified is 16/21.

StartFraction 10 over 20 EndFraction = StartFraction x over 1,500 EndFraction. StartFraction 10 times 30 over 20 times 30 EndFraction = StartFraction x over 1,500 EndFraction. 300 = x.
He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.
He did not multiply the numerator and denominator by the correct number to equal 1,500.
His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion.
He can only solve the proportion by multiplying the numerator and denominator by a common multiple.
He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500.

What value of y makes the equation true?
3(2y + 3) = 9y - 15
Answers
Answer:
8
Step-by-step explanation:
First, distribute the 3 on the left side of the equation:
6y + 9 = 9y - 15
Next, move the variables to one side of the equation and the constants to the other:
6y - 9y = -15 - 9
Simplifying the left side:
-3y = -24
Finally, solve for y by dividing both sides by -3:
y = 8
Therefore, the value of y that makes the equation true is 8.

in the next question you have to find the perimeter from the area. the area is length times width and the shape is a square. Therefore, just figure out what number squared is equal to 64m^2, which would be 8m. You then multiply 8m by 4 which gets you 32m. 32m is the perimeter of the square.
the shape on the very right is just 5*6, so the area of that is 30. the other shape, to find the sides, just do (6+6)(10-5) which simplifies to 12*5. 12*5= 60 and when you add 30 to that you get the final area of the figure, 90cm.
