Answer:
Step-by-step explanation:
i think both are false.
Triangle ABC has vertices A, B and C at points (-3,4), (-3,0) and (-1,3), respectively.
1. First transformation is rotation by 90° anti-clockwise about the origin. This transformation has a rule:
(x,y)→(-y,x).
Then
- A(-3,4)→A''(-4,-3);
- B(-3,0)→B''(0,-3);
- C(-1,3)→C''(-3,-1).
2. Second transformation is translation 2 units to the right with a rule
(x,y)→(x+2,y).
Then,
- A''(-4,-3)→A'(-2,-3);
- B''(0,-3)→B'(2,-3);
- C''(-3,-1)→C'(-1,-1).
Answer: First transformation is rotation by 90° anti-clockwise about the origin, second transformation is translation 2 units to the right.
65. change 11 5/6 to a mixed number:
71/6-17/18
multiply 6 and 71 by 3 which equals 18 so now the denominators are the same
213/18-17/18=196/18
to simplify divide 196 and 18 by 2
196÷2=98
18÷2=9
now divide 98 by 9
98÷9=10 (rounded to whole number)
9×10=90
so to get 98 you add 8
your answer is 10 8/9
66. change both fractions to a mixed number
9 5/9=86/9
8 1/6=49/6
multiply 86 and 9 by 2
86×2=172
9×2=18
multiply 49 and 6 by 3
49×3=147
6×3=18
now subtract :
172/18-147/18=25/18
divide 25 by 18
25÷18=1 (rounded whole number)
18×1=18
to get 25 you add 7
your answer is 1 7/18
hope this helped
