Step-by-step explanation:
1/2(6-y)=4
Distribute. 3-1/2y=4
Subtract. -1/2y=1
Divide. Y=-2
Answer:
9+7+4+5= 25
Step-by-step explanation:
add up everything then get ur answer
Note the coordinates of each point: R(-4, 5), S(5, 1), T(2, -3).
The centroid is the point whose coordinates are the average of the coordinates of R, S, and T.
<em>x</em>-coordinate: (-4 + 5 + 2)/3 = 3/3 = 1
<em>y</em>-coordinate: (5 + 1 - 3)/3 = 3/3 = 1
So the centroid is (1, 1).
