3(x + 1) - 2x = -6    |use distributive property: a(b + c) = ab + ac

3x + 3 - 2x = -6

x + 3 = -6    |subtract 3 from both sides

x = -9

yKpoI14uk [10]

Answer:

The reason for the columns adding up to 1 is that each individual consumes a proportion or a fraction of the total quantity produced under each product category and every product is consumed.  There is no leftover.

When the proportions of all the individuals are added up, the sum is always 1 under each product category because each individual can only consume a part of the whole.

A company determined that the marginal​ cost, C' (x )of producing the xth unit of a product is given by C' (x )= x^3- 6x. Find t
Rashid [163]

Answer:

C(x) = \frac{x^4}{4}-3x^2+3,000

Step-by-step explanation:

The marginal cost function, C'(x), is the derivate of the cost function, C(x).

Therefore, we can obtain the cost function by finding the integral of the marginal cost function:

C(x) = \int\ {C'(x)} \, dx \\C(x) = \int\ {(x^3-6x)} \, dx \\C(x) = \frac{1}{4} x^4-3x^2+a

Where 'a' is a constant and represents fixed costs. If fixed costs are $3,000, the cost function is:

C(x) = \frac{x^4}{4}-3x^2+3,000

A statue that is 80 m tall stands on a 625 m2 base. An artist creates a replica using a ratio of 1:15. What is the area of the r
Sholpan [36]

Answer: 2.78m^{2}

Step-by-step explanation:

given data:

height of the statue = 80m.

base of the statue = 625m^{2}.

scale of the statue replica = 1:15.

<u><em>solution:</em></u>

= 1:15^{2} \\\\\= 1:225\\\\

= \frac{625m^{2} }{225}

= 2.78m^{2}

the area of the replica is 2.78m^{2}
