Answer:
D
Step-by-step explanation:
Two lines are perpendicular when the product of their slopes = - 1
line 1: y = 3x + 4
(3 , 0) ; (-3,2)
Slope of line 1 = 3
Slope of line 2 = -1/3
3* -1/3 = -1
Answer:
D) Commutative property of addition
Step-by-step explanation:
Commutative property of addition
a + b = b + a
On this case
-12 + 5x = 5x - 12
Answer
D) Commutative property of addition
Answer:
20.8
Step-by-step explanation:
The chord with length x is bisected by the perpendicular segment.
Use the Pythagorean theorem to find the length of half of x.
Let's call half of x, y.
y^2 + 6^2 = 12^2
y^2 = 144 - 36
y^2 = 108
y = sqrt(108)
x = 2y = 2sqrt(108)
x = 20.8
