A. 1/2(140-100) = 20
X = 20
B. 4^2 = 3 (x+3)
16 = 3x + 9
X = 7/3
Answer:
A
Step-by-step explanation:
When planes intersect, it means they'll cross over each other at some point, so A is the only right answer.
Answer:
The one in the top left corner and bottom middle
Given:
Point k is located on the y-axis 8 units away from the origin.
To find:
The coordinates of point k.
Solution:
Since point k is located on the y-axis, therefore it means the x-coordinate is 0.
Point k is 8 units away from the origin. So, it can be either or positive or negative side of y-axis.
If k is on the negative side of y-axis then y-coordinate of point k is -8.
If k is on the positive side of y-axis then y-coordinate of point k is 8.
Therefore, the possible coordinates of point k are either (0,-8) or (0,8).
