Im pretty sure it’s 12 miles, hope this helped :)
Answer: 4y/(y+3)
Explanation:
{(2y)(4y-12)}/{(y-3)(2y+6)}
= (8y^2 - 24y)/(2y^2 + 6y - 6y - 18)
= (8y^2 - 24y)/(2y^2 - 18)
= {8y(y-3)}/{2(y+3)(y-3)}
= 2 * 4y/{2(y+3)}
= 4y/(y+3)
Given:
Endpoints of segment AB are A(- 18, 5) and B(- 4, 5).
Point Z is located exactly 1/8 of the distance from A to B.
To find:
The value of the x-coordinate of point Z.
Solution:
Point Z is located exactly 1/8 of the distance from A to B.
AZ:AB=1:8
AZ:ZB = AZ:(AB-AZ)= 1:(8-1) = 1:7
It means point Z divided segment AB in 1:7.
Using section formula, the x coordinate of point Z is
![x-coordinate=\dfrac{mx_2+nx_1}{m+n}](https://tex.z-dn.net/?f=x-coordinate%3D%5Cdfrac%7Bmx_2%2Bnx_1%7D%7Bm%2Bn%7D)
![x-coordinate=\dfrac{1(-4)+7(-18)}{1+7}](https://tex.z-dn.net/?f=x-coordinate%3D%5Cdfrac%7B1%28-4%29%2B7%28-18%29%7D%7B1%2B7%7D)
![x-coordinate=\dfrac{-4-126}{8}](https://tex.z-dn.net/?f=x-coordinate%3D%5Cdfrac%7B-4-126%7D%7B8%7D)
![x-coordinate=\dfrac{-130}{8}](https://tex.z-dn.net/?f=x-coordinate%3D%5Cdfrac%7B-130%7D%7B8%7D)
![x-coordinate=-16.25](https://tex.z-dn.net/?f=x-coordinate%3D-16.25)
Therefore, the required x-coordinate of point Z is -16.25.
Answer:
Event A = white marble is selected
Event B = blue marble is selected
P(A) = 5/10 = 1/2
p(B) = 5/10 = 1/2
Probability that A and B are independent events is:
P(A∩B) = 1/2 × 1/2
Answer: 1/4
Answer:
your answer is 7.4 X 104 and if you further multiply then you will get 769.6
