Answer:
<u>Colinear points</u>: Points that lie on the same line.
<u>Coplanar points</u>: Points that lie in the same plane.
<u>Plane</u>: a flat, 2D surface with no height.
1. Three colinear points: A, B, E
2. Four coplanar points: A, B, C, E
3. A plane containing E: plane S
4. Two points and a line that lie in Plane T: Points F & G, Line L
5. Two planes that contain l: S and T
Answer:
Triangle B
Step-by-step explanation:
The scale factor is less than 1, so applying that to a geometric figure will make is smaller. Since the smaller triangle is A, it is the result of applying the scale factor to original triangle B.
Answer:
{12, 16}
Step-by-step explanation:
The difference of two <em>numbers (x and y)</em> is 4. Thus, if y is the larger, then y - x = 4. Also, y = 2x - 8.
So we need to solve the system of linear equations
y - x = 4
y = 2x - 8
Subbing 2x - 8 for y, in the first equation, we get (2x - 8) - x = 4, or
x - 8 = 4, and conclude that x = 12. Then, because y - x = 4, y must be 16.
The numbers are 12 and 16.
Answer:
<h2>9</h2>
Step-by-step explanation:
The formula of a distance between x and y:
d = |y - x|
We have x = -4 and y = 5.
Substitute:
d = |5 - (-4)| = |5 + 4| = |9| = 9
Answer:
15
Step-by-step explanation:
The total part of purple paint is the sum of the blue paint aprts nad the red paint parts.
There are:
-3 blue parts
-12 red parts
To find the total purple paint parts we add these together to get:
![3+12 = 15](https://tex.z-dn.net/?f=3%2B12%20%3D%2015)
So there are 15 total purple parts!
Hope this helps! :3
