The answer is 1/7n + 32/21
Answer:
13
Step-by-step explanation:
You need an even number of reflections to get the original figure, leaving only A and D as potentially viable choices.
The reflection across the x-axis makes the tranformation (x, y) ⇒ (x, -y).
The reflection across the line y=x makse the transformation (x, y) ⇒ (y, x).
The two pairs of transformations of A give
(x, y) ⇒ (x, -y) ⇒ (-y, x) ⇒ (-y, -x) ⇒ (-x, -y) . . . . . not the original
The reflection across the y-axis makes the transformation (x, y) ⇒ (-x, y).
The two pairs of transformations of D give
(x, y) ⇒ (y, x) ⇒ (y, -x) ⇒ (-x, y) ⇒ (x, y) . . . . . . the original point
Selection D is appropriate.
Isolate the x.
8x - 6 > 12 + 2x
Add 6 to both sides, and subtract 2x from both sides
8x (-2x) - 6 (+6) > 12 (+6) + 2x (-2x)
8x - 2x > 12 + 6
Simplify. Combine like terms
8x - 2x > 12 + 6
6x > 18
Isolate the x. Divide 6 from both sides
6x/6 > 18/6
x > 18/6
x > 3
Any number that is greater than 3 (3 not included), is your answer.
5 is your answer
