Factor the polynomial by grouping. 12x^x+x−13
tekilochka [14]

Answer:

  (x -1)(12x +13)

Step-by-step explanation:

You are looking to rewrite the middle term as the sum of terms that have factors of (12)(-13) that have a total of +1. Those factors are -12 and +13, so the expression you are factoring by grouping is ...

  12x^2 +13x -12x -13

  = x(12x +13) -1(12x +13)

  = (x -1)(12x +13)

Find an equation for the line below. Thanks !
daser333 [38]

Answer:

\huge\boxed{y=\frac{1}{4}x + \frac{13}{4}}

Step-by-step explanation:

In order to find the equation to this line, we need to note that we see two points on this graph. Using these two points, we can use them to find the slope of the graph and use one to find the y-intercept.

We know that the slope of a line is defined by \frac{\Delta y}{\Delta x} (change in y / change in x). Therefore, we can use our two points that we know - (-5, 2) and (3, 4) to find the slope.

The change in y is 4 - 2 = 2, and the change in x is 3 - (-5) = 3+5= 8. Therefore, our slope is \frac{2}{8} = \frac{1}{4}.

Now that we know our slope, our equation in slope-intercept form looks something like this.

y = \frac{1}{4}x + b

However, we still have b to solve for. We can solve for this by substituting a point we already know into the equation. Let's substitute (3, 4) inside.

  • 4 = \frac{1}{4} \cdot 3+b
  • 4 = \frac{3}{4} + b
  • b = \frac{16}{4}- \frac{3}{4}
  • b = \frac{13}{4}

So now we know that the y-intercept is \frac{13}{4}. Plugging that into our equation finishes it off, leaving our final equation to be y = \frac{1}{4}x + \frac{13}{4}.

Hope this helped!
