Answer:
Step-by-step explanation:
(-1,5) (0,2)
y2= 2, y1 = 5, x2 = 0, x1 = -1
Slope m = [y2 - y1]/[x2 - x1]
m = {2 - 5}/{0+1}
m = -3/1
m = -3
And
y - y1 = m(x - x1)
y - 5 = -3(x + 1)
y - 5 = -3x - 3
y = -3x - 3 + 5
y = -3x + 2
Answer:
1.57
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
6x+x-8=6x+6
Combine like terms
7x -8 = 6x+6
Subtract 6x from each side
7x-6x-8=6x-6x+6
x-8 = 6
Add 8 to each side
x-8+8 = 6+8
x = 14
<h3>Answer:</h3>
6 in
<h3>Explanation:</h3>
Let M be the midpoint of AB. ∆CMB and ∆CMA are both isosceles triangles, so CM = (AB)/2 = 9 in.
CG = (2/3)(CM) = (2/3)(9 in)
CG = 6 in

<em>Comment on centroid and median</em>
The centroid of a triangle is located 1/3 the distance from the midpoint of a side to the opposite vertex. This is true for any median in any triangle. The proof can be developed from the fact that every median divides the triangle's area in half. Here, we just take advantage of this fact.
