Graphing functions <br> f(x)=x^2-6x-27/x+3
hammer [34]
Funny, this looks like a complex graph, until you realize that the numerator can be written like (x+3)(x-9).

So really, this is a straight line f(x) = x-9.

But wait, there's a catch. x≠3, because that would divide by zero. So in your straight line, you have to draw a "hole" at (3,6)

Calculate dy/dx<br> You need not expand your answer.<br><br> y=3x^2-9x+13/2x+4 ...?
grandymaker [24]
The solution to the problem is as follows:

The quotient rule is ( f'(x)g(x)-f(x)g'(x) )/ (g(x))^2 {complex written on 1 line I know} 

let f(x)=9x +13 and g(x)=2x+4 
<span>
f'(x)=9 and g'(x)=2 </span>
<span>
therefore just substitute the equations in. </span>
<span>
y'= 6x - ((9(2x+4)-2(9x+13))/((2x+4)^2)) 
</span>

A test was given to a group of students. The grades and gender are summarized below
jasenka [17]

Answer:

<h3>★ <u>11/30</u> is the right answer. ★</h3>

Step-by-step explanation:

  • Number of male students who got 'A' in the test is 11
  • Number of female students who got 'A' in the test is 19
  • Total students who got 'A' in the test is 30
  • Probability that the male student got an 'A' is P(A | male) = (Number of male students who got 'A' in the test)/(Number of total students who got 'A' in the test) = <em><u>11/30</u></em>

The point below will be reflected over the line y = x and then translated two units left and one unit up.5421-5-4-3-2-10234-1-2-
charle [14.2K]

A reflection over the line y=x implies exchanging the x and y coordinates of a point. For example if you take a generic point (a,b) then its reflection over y=x is (b,a). Our point is (-1,3) so its reflection over y=x is the point (3,-1).

Then we have to translate it two units left. Translating a point left means that we are moving towards negative x values so we need to substract 2 from the x coordinate:

(3,-1)\rightarrow(3-2,-1)=(1,-1)

Finally we have to translate it 1 unit up towards positive y values so we have to add 1 to its y coordinate:

(1,-1)\rightarrow(1,-1+1)=(1,0)

And these are the final coordinates. In the following picture you have the points you get after each step (from A to D) with the y=x line in blue:
