The vertices of a triangle are (11,9), (7,4), and (1,11). What are the vertices after the triangle has been reflected over the y-axis?
(-9,-11), (-4, -7),(-11,-1)
(9,11),(4,7), (11,1)
(-11,9), (-7,4),(-1, 11)
(11,-9), (7,-4), (1, -11)

12cm

the answer is d

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
