Answer:
Step-by-step explanation:
5x -x + 3x =30, first you combine like terms 5x + 3x-x=30
8x-x =30
8-1=7
7x=30
Answer:
On a coordinate plane, a triangle has points (negative 4, 3), (negative 4, negative 2), (1, negative 2).
Step-by-step explanation:
The points (-4,3), (1,2) and (-4, -2) would form a right triangle when graphed and connected by lines.
(-4,3), (1,2) and (1,3) would also work as well
Use Google or Wolfram Alpha
Given:
The coordinates of point K' are (6,5).
K' is the image of K after a reflection in the line y=2.
To find:
The coordinates of point K.
Solution:
Let the coordinates of point K are (a,b).
If a figure is reflected over the line y=2, then
Using this formula, the coordinates of image of K are

The coordinates of point K' are (6,5).

On comparing both sides, we get




Therefore, the coordinates of point K are (6,-1).
