Answer: -20, 6, 2, 5
Step-by-step explanation:
a = 5, b = -4, c = 10
12. ab = 5(-4) = -20
13. b + c = -4 + 10 = 6
14. c/5 = 10/5 = 2
15. c - 5 = 10 - 5 = 5
<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.
Answer:
-5 and 12
Step-by-step explanation:
Answer:
Step-by-step explanation:
slope is the x axis and y intercept is the y axis
so 1/2 will go on the x axis and -9 will go on the y axis
1/2 uses the rise over run method
