G(-2, 5), H(6, 5), J(6, -1)<br> 17. Find the coordinates of the centroid.

adell [148]

The coordinates of centroid are: (10/3, 3)

Step-by-step explanation:

The formula for calculating centroid of a triangle is:

$(x,y) = (\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3})$

Here (x1,y1) are the coordinates of first vertex

(x2,y2) are the coordinates of second vertex

(x3,y3) are the coordinates of third vertex

Given:

G(-2,5) = (x1,y1)

H(6,5) =(x2,y2)

J(6,-1) = (x3,y3)

Let I be the centroid of the triangle

Putting the values in the formula

$I(x,y) = (\frac{-2+6+6}{3},\frac{5+5+-1}{3})\\= (\frac{10}{3},\frac{9}{3})\\=(\frac{10}{3},3)$

The coordinates of centroid are: (10/3, 3)

Factor by grouping : xy + 6y - 2x - 12 (if you don't know the answer don't comment)

alexira [117]

<h3> Hey There today we will solve your problem</h3>

First we will factor out $y$ from $xy+6y$ which gives us $y(x+6)$

Next we will factor out $-2$ from $-2x-12$ which gives us $-2(x+6)$

This gives us the equation

$y(x+6)-2(x+6)$

then factor out the common term $x+6$ <em> and we get</em>

<em /> $\left(x+6\right)\left(y-2\right)$
