Dafna11 [192]
I think 6 because it’s a ratio

Because the yellow would always be twice as much as the red so 3x2 is 6 just like 6x2=12

The second step in the process for factoring the trinomial is to:
emmainna [20.7K]
Example:  <span>the second step in the process for factoring the trinomial x^2-3x-40 is to:</span> <span>Well you really should find the sum of the factors of −40 (not 40) </span>
<span>But before you can do that, you need to LIST the factors of −40 (not 40) </span>
<span>−1 * 40 </span>
<span>−2 * 20 </span>
<span>−4 * 10 </span>
<span>−5 * 8 </span>
<span>−8 * 5 </span>
<span>−10 * 4 </span>
<span>−20 * 2 </span>
<span>−40 * 1 </span>

<span>NOW we find the sum of the factors of −40 </span>
<span>−1 + 40 = 39 </span>
<span>−2 + 20 = 18 </span>
<span>−4 + 10 = 6 </span>
<span>−5 + 8 = 3 </span>
<span>−8 + 5 = −3 </span>
<span>−10 + 4 = −6 </span>
<span>−20 + 2 = −18 </span>
<span>−40 + 1 = −39 </span>

<span>Then we choose the factors of −40 whose sum is −3 ---> −8 and 5 </span>
<span>x^2 − 3x − 40 = (x − 8) (x + 5) </span>

<span>So FIRST step is B, SECOND step is C, and final step is factoring. </span>
What Rita did was combine these 2 steps together, which you will learn to do as you get better at factoring.

I am soooo confuseddd what the heckkk Ok so Im doing something called 'Graphing Systems of Linear Equations' , well you might sa
horsena [70]
Okay, so the equation for the y-intercept is y=mx+b, this will be your base for graphing anything.

For y = x + 3 it's basically y = 1x + 3. Use b as the y-intercept, or 3, and plot it as (x,y), (0,3). Then use m as the slope, or 1. 1 means positive one so the point goes (0,3), (1, 4), (2, 5).

For y = -3x - 1 it's the same thing but different numbers. Use b, the y-intercept, and plot it. -1 is b, so plot (0,-1). Then use the slope to go up or down the direction you need to go, or m. m is -3, so for every +1 in x, the y will decrease by 3. (0,-1), (0,-4), (0,-7).

I hope this helped in some way or increased your understanding!

What percent of 20 is 6
Luba_88 [7]

Answer:  30 percent of 20 is 6.

_______________________________________________

Step-by-step explanation:

_______________________________________________

(n/100)  * 20 = 6  ?  

Solve for "n"  .

_______________________________________________

Divide each side of the equation by "20" :

{ (n/100) * 20 }  / 20  = 6 / 20 ;

to get:

n/100  = 6/20 ;  

↔ 6/20 = n/100 ; solve for "n" ;

Look at the denominators:


20 * ? = 100 ?

  100/ 20 = ?  ;

  100/20 = 5 ;


So, 20 *  " 5" = 100 ;

Then 6* 5 = "n"  (for the numerator, "n";  in  :   "n /100" ) ;

                  →  6 * 5 = 30 ;

                  →  n = 30 .

_______________________________________________

 Answer:  30 percent of 20 is 6.
