x^2 - 12x + 35

Answers

Answer 1

Answer:

Answer:

(x + 3)(5x + 2)

Step-by-step explanation:

${x}^(2) - 12x + 35 \n {x}^(2) - 7x - 5x + 35 \n = x(x - 7) - 5(x - 7) \n = (x - 7)(x - 5)$

The demand d for a companys product cost x is predicted by the function d(x) = 500-2x. The price p in dollars that the company can charge for the product is given by p(x)=x+5

Answers

Answer:

Step-by-step explanation:

The Break Even point is the point at which the cost=revenue

14,980+20x=30x

14,980=10x

1,498=x

a. 1,498 units must be sold to break even. At $20 per unit, the dollar amount will be $29,960

b. The profit function is P(x)=R(x)-C(x)

So P(x)=30x-(14,980+20x)

If you want to solve for this equation just enter the value of x we found for the break even point to get the answer.

Final answer:

The student is given two functions, d(x) = 500-2x and p(x) = x+5, which represent the demand and price, respectively, of a company's product. To find the relationship between price and quantity, we can substitute the demand function into the price function.

Explanation:

The subject of this question is Mathematics. The student is given two functions, d(x) = 500-2x and p(x) = x+5, which represent the demand and price, respectively, of a company's product. To find the relationship between price and quantity, we can substitute the demand function into the price function:

p(x) = x + 5 = d(x) + 5 = (500 - 2x) + 5 = 505 - 2x

So the price can be represented by the equation p(x) = 505 - 2x.

the area of a pentagon increased by 27 is the same as four times the difference of area and 15. what is the area of the pentagon?

Answers

this can be written as:
a+27=4(15-a)
now to work it out
a+27=4(15-a)
a+27=60-4a
4a+27=60
4a=33
a=8.25

thomas and his mom take a taxi to the airport it costs a flat fee of $10 plus $4.75 a mile his mom adds a 10% tip to the total and pays the diver $58 what is the distance to the airport

Answers

This is one of those problems that you have to work backwards ...
start with the total, and work back to the parts that make it up.

-- The total is $58 .

-- The tip was 10% of the total fare.
   So
    1.10 (total fare) = 58

Divide each side by 1.1 : Total fare = 58/1.1 = $52.73

Out of the total fare, $10 was the flat fee before they drove
anywhere. So the amount for mileage was $42.73 .

Mileage was charged at the rate of $4.75 per mile.
So the distance was
   42.73 / 4.75 = 9.00 miles (rounded)

1.1(10 + 4.75x) = 58
10 + 4.75x = 580/11
4.75x = 470/11
4 3/4 x = 470/11
19/4x = 470/11
x = 470/11 * 4/19
= around 9 miles

Mr. Ishimoto ordered x new math books and y new workbooks for his class. The total weight of the box of books cannot be more than 50 pounds. If each math book weighs 3.2 pounds and each workbook weighs 0.8 pounds, which inequality represents the maximum number of each type of book that can be shipped in a single box?

Answers

Unfortunately, there are no given choices. However, I could provide the possible inequalities from the given problem. Converting the given to inequalities: 3.2x + 0.8y < 50 x + y = maximum There is no other limiting equation (i.e. the total cost of the books) such that the, if you wanted to maximize x, results to minimum y and vice versa.
