A stand was selling 8 mangos for 10 dollars at a farmer's market.
MaRussiya [10]
(Ms)Kisha is correct.

How?

Well, I figured this out by using common sense. 8 mangoes are 10 dollars. Since the price is higher than the amount, so it has to be at least more than one.

We could write more ratios. You can always write more ratios. You just multiply/divide both sides. Examples below:
2:5
16:20

If f(x) = -x-2, what is f¹(x)?
astra-53 [7]

Answer:

  1. f¯¹(x) =9x+18, for the pictorial(image) question
  2. what is the send question is it asking derivative or inverse
  3. If it is inverse f¯¹(x)=-x-2 as it is
  4. Or if it is derivative f'(x)=-1

Step-by-step explanation:

<h2>For the image question f(x)=1/9x-2,f¯¹(x)=?</h2>
  • f(x)=1/9x-2............given
  • y=1/9x-2................swapping f(x) by y to Easily write
  • x=1/9y-2................interchanging x and y
  • 1/9y-2=x................changeling side of equation
  • 9(1/9y-2)=(x)9.......multiplying both sides by 9 to override the fraction on the right side
  • y-18=9x
  • y=9x-18.................Return to where it were
  • <em><u>f¯¹(x)=9x+18</u></em>..........swap back f¯¹(x) in the y

<h2>For the question f(x)=-x-2,f¯¹(x)=?</h2>
  • following the ☝️ arrangement
  • y=-x-2
  • x=-y-2
  • -y-2=x
  • -y=x+2
  • y=-x-2
  • f¯¹(x)=-x-2

Kryger [21]

Answer:

\large\boxed{\dfrac{10x^6y^3+20x^3y^2}{5x^3y}=2x^3y^2+4y}

Step-by-step explanation:

\dfrac{10x^6y^3+20x^3y^2}{5x^3y}=\dfrac{(5x^3y)(2x^3y^2)+(5x^3y)(4y)}{5x^3y}\\\\=\dfrac{5x^3y(2x^3y^2+4y)}{5x^3y}\qquad\text{cancel}\ 5x^3y\\\\=2x^3y^2+4y
