Step-by-step explanation:
the centroid is where the medians intersect.
On each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint.

GF =
CG =
× 14 = 7
CF = CG + GF = 14 + 7 = 21
(4)
GD =
AD =
× 45 = 15
AG = 2 × GD = 2 × 15 = 30
(5)
GE = 2 × BG , that is
9x = 2(3x + 6) = 6x + 12 ( subtract 6x from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Answer:
yes
Step-by-step explanation:
Change the second equation into slope-intercept form: y+3=-3(-x+2)
Distribute the -3: y+3=3x-6
Isolate the y: y=3x-6-3
Simplify: y=3x-9
Since they have the same slope, they are parallel
