Answer:
y = 2x - 20
Step-by-step explanation:
Simplfy 2 (x-1)
y + 18= 2x - 2
move all terms contain "y" to the left side
y = 2x - 20
Answer:
2 , 3
Step-by-step explanation:
Answer:
That is 200.
Step-by-step explanation:
You have to simply multiply 10 * 20
Answer: x = 30
==========================================================
Explanation:
When adding three angles of any triangle, they always add up to 180
3x+2x+x = 180
6x = 180
x = 180/6
x = 30
This then means,
- 3x = 3*30 = 90
- 2x = 2*30 = 60
This triangle is a 30-60-90 triangle.
The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
<h3>
How to rotate the triangle?</h3>
The coordinates of RST are given as:
R = (5,15)
S = (15,15)
T = (10,5)
The rule of 90° counterclockwise around the origin is:
(x,y) -> (-y,x)
So, we have:
R' = (-15,5)
S' = (-15,15)
T' = (-5,10)
Hence, the image of the triangle when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
