Answer:

49

Step-by-step explanation:

The cost function is the sum of the costs as a function of the number of bins made.

C(x) = 4x + 18424

The profit function is the difference between the revenue and the cost functions.

P(x) = R(x) - C(x)

P(x) = -2x^2 + 478x - (4x + 18424)

P(x) = -2x^2 + 474x - 18424

The smallest break-even point is the smallest value of x at which profit is zero. Zero profit means there is no gain and no loss.

P(x) = -2x^2 + 474x - 18424 = 0

x^2 - 237x + 9212 = 0

9212 = 2^2 * 7^2 * 47

(x - 188)(x - 49) = 0

x - 188 = 0 or x - 49 = 0

x = 188 or x = 49

Answer: 49

Maya is packing her backpack for hike in one pocket she puts in 1/4 pound bag of trail mix a water bottle weighing 2 1/5 pounds
xz_007 [3.2K]
This problem is simply asking us to add the weights which are presented as fractions. You can easily get the answer if you input them directly in a calculator. But I think the challenge here is to manually add fractions.

Let's add the two 1/4 lb weights because it is easier for they have a common denominator. Just simply add the numerators.

1/4 + 1/4 = 2/4

Then, add with this the fraction part of 2 1/5.

2/4 + 1/5 = ?
The least common denominator is 4*5 = 20. Then divide 20 with each denominator and multiply to their respective numerator.

2/4 + 1/5 = [(20/4 * 2) + (20/5 *1)]/20 = 14/20

14/20 is simplified to 7/10. Then add the whole number 2. <em>Therefore, the sum of all weights is 2 7/10 pounds.</em>

Factoring , <br> a² +4a - 5
givi [52]

the factors of the term a^2+4a-5 are (a-1)(a+5)

Step-by-step explanation:

We need to find factors of the term: a^2+4a-5

For finding factors:

We need to break the middle term such that their product is equal to product of first and last term and their sum is equal to middle term

Breaking the middle term and finding factors:

a^2+4a-5

=a^2+5a-a-5

=a(a+5)-1(a+5)

=(a-1)(a+5)

So, the factors of the term a^2+4a-5 are (a-1)(a+5)

Twice x, plus 7, is the same as – 10.<br> The answer is N
sergij07 [2.7K]

Answer:

x=-8.5.

Step-by-step explanation:

First, write an equation. Twice x (2x) plus 7 (+7) is the same as (=) negative ten (-10), or 2x+7=-10. To solve, first subtract 7 from both sides to get 2x=-17. Then, divide both sides by 2 (x=-8.5).
