Answer:
x - y = 5
x + y = 23
x = 14, y = 9
Step-by-step explanation:
Make x subject:
x = 5 + y
Substitute c by (5 + y) :
( 5 + y) + y = 23
2y = 18
y = 9
Substitute y (9):
x = 5 + 9
x = 14
1. First transformation is rotation rotation of 180 about the origin. This transformation has a rule:
(x,y)→(-x,-y).
If points E(-2,-4), F(-1,-1), D(-2,-1) are vertices of triangle EFD, then
- E(-2,-4)→E''(2,4),
- F(-1,-1)→F''(1,1),
- D(-2,-1)→D''(2,1).
2. Second transformation is translation 1 unit left with a rule
(x,y)→(x-1,y).
Then
- E''(2,4)→E'(1,4),
- F''(1,1)→F'(0,1),
- D''(2,1)→D'(1,1).
Answer: 1st: rotation of 180 about the origin; 2nd: translation 1 unit left.
