f(x) = 112 - kx
f(-3) = 112 - k(-3)
f(-3) = 112 - (-3k)
f(-3) = 112 + 3k
121 = 112 + 3k
- 112 - 112
9 = 3k
3 3
3 = k
Answer:
Triangle Proportionality Theorem
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally
Answer:
Step-by-step explanation:
The acute angles of a right-angled triangle other than the right angle always add up to 90 degrees.
<u>So, we get:</u>
(48 - x) + (3x - 10) = 90
48 - x + 3x - 10 = 90
-x + 3x - 10 + 48 = 90
2x + 38 = 90
2x = 90 - 38
2x = 52
Divide both sides by 2
x = 52 / 2
x = 26

Mid point b/w (18,-6),(0,0)
X = 0+18/2 = 9
y = 0-6/2 = -3
thus mid point is (9,-3)
