Answer: The length of BD is 9
Step-by-step explanation: The length of the segment from the vertex to the centroid is twice the length of the segment from the centroid to the midpoint on the side opposite the vertex
In other words, the length of BE is 2/3 the length of BD. let x be the length
6 = 2/3 x
3/2(6) = x
9 = x
We can write the equation in point-form in this case. The equation should be:
y-y1 = m(x-x1)
y and x can be any point in the line, so we leave them just like that in the equation, we don’t have to add any numbers to them. m is the slope of the line, and (x1, y1) is the given point in the line, which is (-1, 1) in this case.
Now, just substitute the number in,
y - 1 = -2 [x - (-1)]
y - 1 = -2 (x+1)
y - 1 = -2x - 2
2x + y + 1 = 0
So, 2x + y + 1 = 0 is your answer.
Answer:
1/16
Step-by-step explanation:
for the first spin the chances of it landing on green is 1/4 and the second time is 1/4 chance it wil land on red. 1/4x1/4=1/16
