Answer:

dy/dx does not exist.

Step-by-step explanation:

If a question asks us to find dy/dx of a equation, it is asking us to find the derivative of a function.

There are two main ways to find the derivative of a function:

  • Use definition (\mathop {\lim }\limits_{h\to0}\frac{{f\left({x+h}\right)-f\left( x\right)}}{h})
  • Use derivative rules (product rule, quotient rule, power rule, exponential rule, etc...)

Something important to remember when finding the derivative of a function:

  • If the equation is in the form g(x) = c (such as x = 1, x² = 5, √x = 4, etc...), where c is a constant, the derivative does not exist. This makes sense, since the derivative of a function is an equation for the slope of a function, and the slope of a function in the form g(x) = c has an undefined slope.

We are given the function y = 3x² + y, and we are asked to find dy/dx. See how the y's on each side cancel out:

y = 3x² + y

-y           -y

0 = 3x²

This is in the form g(x) = c, where c = 0 and g(x) = 3x². There is no derivative to this function. Therefore, dy/dx does not exist.

I hope this helps. :)

19 is 6% of what number?
Lilit [14]
You have to be able to take the words written down and put them into mathematical symbols.  The word "is" means =, the word "of" means to multiply, "what number" is x, your unknown.  So translating that from words to an equation looks like this: 19 = .06x.  Divide both sides by .06 to get x = 316 2/3

Write the expression in WORDS!<br><br> 5x + 3
Svet_ta [14]
The expression 5x+3 would be three more than five times a number! More than in this case would be addition - so if you get the same problem with subtraction you just change more to less!
Basically what it's tell you is that if x stood for 2 in this case 5*2 = 10 since it's 3 MORE than 5 times a number (x is in place of a number), you're adding 3 to 10 and that gives you 13!
I hope I simplified it a little more and you understand!
Good luck, rockstar! c: I hope this helped!

Armando used algebra tiles to represent the product 3 x (2 x minus 1). An algebra tile configuration. 3 tiles are in the Factor
EleoNora [17]

Answer:

Some of the products do not show the correct powers of x.

Step-by-step explanation:

From the picture,

3x(2x - 1) = 6x² - 3x

The correct display on the tile should look like this :

_____+x ______ +x ______ +x

+x __ +x² ______+x² ______+x²

|

+x__ +x² ______ +x² ______+x²

|

- ___ -x _______ -x _______-x

+6x² - 3x
