What two numbers multiply to -96 and add to 20
anygoal [31]
xy=-96\\
x+y=20\\\\
xy=-96\\
x=20-y\\\\
(20-y)y=-96\\
20y-y^2=-96\\
y^2-20y-96=0\\
y^2-24y+4y-96=0\\
y(y-24)+4(y-24)=0\\
(y+4)(y-24)=0\\
y=-4 \vee y=24\\\\
x=20-(-4) \vee x=20-24\\
x=24 \vee x=-4\\\\
(x,y)\in\{(24,-4),(-4,24)\}

So these numbers are -4 and 24.

Graph the rational function <br> f (x)=- 3x + 1<br> -x+2
Nataly_w [17]

Answer:

Step-by-step explanation:

You must show that this is a rational function.  As written, it is not such.

         -3x + 1

f(x) = ------------

           -x + 2

is a rational function; the horizontal line --------- indicates division.

If we let x grow large, the graph approaches the horizontal line y = 3, which we call "the horizontal asymptote."  There is a vertical asymptote at x = 2, which we know because the denominator will be zero at that x value.  The vertical intercept is

f(0) = 1/2, or (0, 1/2).

As x decreases towards negative infinity, the graph approaches the horizontal line (horizontal asymptote) y = 3.

Quadratic factorisation Question, help please.
luda_lava [24]
3x^2 + 5x + 2 

a = 3 , b = 5 , c = 2 

Start by mulitplying a*c = 3 * 2 = 6

Now find two number that multiply to 6 and add up to b or 5 

We could use 2 and 3 because ....

   
3 + 2 = 5 
   3 * 2 = 6

Now you rewrite....

3x^2 + 3x + 2x + 2 

Now pull out common factors...

3x ( x + 1 )  + 2 ( x + 1)

The factors of this expression is ( 3x + 2 ) ( x + 1)
