What is the simplified form of the expression? c^9d^-7/c^14d^-10
Softa [21]
Just as same-base exponents can be added when multiplied, you should subtract the exponent when the numbers are being divided:

\frac{c^9d^{-7}}{c^{14}d^{-10}} = c^{(9-14)}d^{(-7+10)} = c^{-5}d^3 =  \frac{d^3}{c^5}

Which expressions are equivalent? Select two answers.
professor190 [17]

Answer:

<h2>A, C</h2>

Step-by-step explanation:

The distributive property:

<em>a(b + c) = ab + ac </em>or<em> a(b - c) = ab - ac</em>

<em></em>

A.\\\\\dfrac{1}{5}(x-50)=\dfrac{1}{5}x-\left(\dfrac{1}{5}\right)(50)=\dfrac{1}{5}x-\dfrac{50}{5}=\dfrac{1}{5}x-10\\\\B.\\\\-\dfrac{1}{3}(3x+18)=\left(-\dfrac{1}{3}\right)(3x)+\left(-\dfrac{1}{3}\right)(18)=-\dfrac{3}{3}x-\dfrac{18}{3}=-x-6\\\\-x-6\neq\dfrac{1}{3}x-6

C.\\\\\dfrac{1}{2}(x+16)=\dfrac{1}{2}x+\left(\dfrac{1}{2}\right)(16)=\dfrac{1}{2}x+\dfrac{16}{2}=\dfrac{1}{2}x+8\\\\D.\\\\\dfrac{1}{8}(8x+8)=\left(\dfrac{1}{8}\right)(8x)+\left(\dfrac{1}{8}\right)(8)=\dfrac{8}{8}x+\dfrac{8}{8}=x+1\\\\x+1\neq\dfrac{1}{8}x+1\\\\E.\\\\-\dfrac{1}{4}(x+2)=-\dfrac{1}{4}x+\left(\dfrac{1}{4}\right)(2)=-\dfrac{1}{4}x+\dfrac{2\!\!\!\!\diagup^1}{4\!\!\!\!\!\diagup_2}=-\dfrac{1}{4}x+\dfrac{1}{2}\\\\-\dfrac{1}{4}x+\dfrac{1}{2}\neq-\dfrac{1}{4}x+2

Business Calc Question: A certain D. Kong is producing and selling bananas. Let p be the price of a bushel of bananas and let x
mylen [45]
I could be wrong because I didn’t take business calculus, but i guess it’s the same as regular calculus.

So I assumed that the revenue is equal to the price times the amount produced: R=px

Now differentiating, I get: dR/dt =pdx/dt +xdp/dx. I used the product rule

But Mr. Kong wants his revenue constant ? So I assume that dR/dt=0

Plug in values and solve dx/dt. Please message me back. I want to see if I got it write
