Answer:

y = (√7)/4

Step-by-step explanation:

The equation of the unit circle is ...

x^2 +y^2 = 1

Putting the given value in for x, we can find y to be ...

(-3/4)^2 +y^2 = 1

y^2 = 1 -(-3/4)^2 = 1 -9/16 = 7/16 . . . . . subtract 9/16

y = √(7/16) . . . . . . . . . . . take the square root; y > 0 here

y = (√7)/4

Which transformations can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4

Romashka [77]

The triangles ABC and A'B'C' are shown in the diagram below. The transformation is a reflection in the line $y=-x$ . This is proved by the fact that the distance between each corner ABC to the mirror line equals to the distance between the mirror line to A'B'C'.
