Answer:

   20/3

Step-by-step explanation:

There are two ways to do this.

1) "invert and multiply" or "dot swap"

  (10/9) ÷ (1/6) = (10/9) · (6/1)

The division is changed to multiplication (dot, ·) and the divisor fraction 1/6 is inverted (numerator and denominator are swapped).

The resulting product is ...

  (10/9)×(6/1) = 60/9 = 20/3

__

2. Use a common denominator. The denominators 9 and 6 of the respective fractions have a least common multiple of 18. This means both fractions can be expressed using 18 as a denominator:

  \dfrac{\text{ }\dfrac{10}{9}\text{ }}{\dfrac{1}{6}}=\dfrac{\text{ }\dfrac{20}{18}\text{ }}{\dfrac{3}{18}}=\boxed{\dfrac{20}{3}}

Once the fractions are expressed with a common denominator, the denominators can be ignored/removed/cancelled. They are equivalent to a factor of (a/a) = 1, where a=1/18.

Step-by-step explanation:

C(x)=mx+b

m-marginal cost

x-no items

finding B

b=2250

General substitution

C(x)=25x+6000

What is the sign of f on the interval -2
TEA [102]

Answer:

f is sometimes positive and sometimes negative.

Step-by-step explanation:

f(x)=(x-3)(x+2)(x+4)(x+4)(x-1)(2x-9)

Take x=-1\in(-2,\frac{9}{2})\ as-2

f(-1)=(-1-3)(-1+2)(-1+4)(-1-1)(-2-9)\\\\=(-4)(1)(3)(-2)(-11)\\\\=-264\\\\f(-1)

Take x=2\in(-2,\frac{9}{2})\ as\ -2

f(2)=(2,-3)(2+2)(2+4)(2-1)(2\times2-9)\\\\=(-1)(4)(6)(1)(-5)\\\\=120\\\\f(2)>0

Hence f(x) for x=-1 and f(x)>0 for x=2

So f is sometimes positive and sometimes negative in the interval.

nordsb [41]

Answer: y=5x+7

Step-by-step explanation:

If you draw a graph or use a graphing calculator the points and then connect them you will see that the y-intercept is 7 and the slope is 5/1. Slope intercpt  form is y=mx+b. So the equation is y=5x+7.
