Flipping a point across the y axis, the y coordinate should flip signs (negative if it was positive before, and vice versa). So
reflection across y axis = (-1 5/7, 1).
Similarly, reflecting across the x axis, the sign will also flip. So
reflection across x axis = (1 5/7, -1).
Because the coin has only two sides, the probability of him getting tails is 1/2, and because of the dice has six sides, the probability of him getting a 3 is 1/6.
31.25/5=50/8. Divide 31.25 by 5 you get 6.25. Divide 50 by 8 you get 6.25. The constant ratio is: 6.25=6.25 :)
The triangle △ABC and △DEC are similar to each other. Then the correct option is A, B, and D.
<h3>What is a transformation of a point?</h3>
A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.
Right triangle ABC is reflected over AC.
Then dilated by a scale factor of Two-thirds to form triangle DEC.
The triangle △ABC and △DEC are similar to each other.
△ABC ≅ △DEC
The dilation is 2/3. Then we have
DE / AB = 2 / 3
3AB = 2DE
∠B ≅ ∠E = 90
There is no effect of dilation on angle.
Then the correct option is A, B, and D.

Answer:
In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign. When seeking a solution, one or more variables are designated as unknowns.
