Please help me Find the values of x and y that make these triangles
congruent by the HL Theorem.

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).

Equation for the calculation double 2 and then add 5
