Answer:
-10,2
Solve by factoring set each equation equal to 0.
2x-4=0
X+10=0
Simplify
4a = 2b-7
(4 x 3) = 2b-7
12 + 7 = 2b (As sign changes over an equals)
19 = 2b
19/2 = b

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).
Find each percent to the nearest percent. State if it is an icrease or a decrease.
