Answer:
G'(1, 3)
Step-by-step explanation:
Counterclockwise rotation 90°: (x, y) ⇒ (-y, x)
So the point G is transformed to ...
... G(3, -1) ⇒ G'(1, 3)
Answer:
x-4y = 8
Step-by-step explanation:
y– 1 =1/4 (x – 12)
Multiply each side by 4
4y -4 = x-12
Subtract x from each side
-x +4y -4 = -12
Add 4 to each side
-x+4y -4+4 = -12 +4
-x+4y = -8
Multiply by -1
x-4y = 8

Answer:
126 degrees
Step-by-step explanation:
Triangle: y = 180 - (5x + 4x)
Straight angle: y = 180 - (4x + 30)
180 - (5x + 4x) = 180 - (4x + 30)
5x + 4x = 4x + 30
5x = 30
x = 6
Angle:
y = 180 - (5x + 4x)
y = 180 - 9x
y = 180 - 9(6)
y = 126
