Answer:
B. Rotate 180° clockwise around (8, 4) and reflect across the line x=8.
Step-by-step explanation:
The figure is symmetrical (order 2) about the point (8, 4), and about the lines x=8 and y=4.
Hence, rotation 180° about the point (8, 4) makes the figure look unchanged. Since the figure is also symmetrical about the line x=8, reflecting it across that line will also leave the figure unchanged.

Any of the other transformations have the effect of translating the figure somewhere else.

Answer: AD = 9cm
Step-by-step explanation: This is a 30-60-90 triangle, so the hypotenuse is equal to twice the length of the short side of the right angle.
BC is the short side of the large triangle, so AB, the hypotenuse of the large triangle is 2×6, 12 cm
BC is also the hypotenuse of the small triangle, ΔBCD, so it is twice the length of BD, to that makes BD = 6/2= 3
Subtract BD from AB.
That's 12 - 3 = 9 the length of AD
Answer:
z < 2
Step-by-step explanation:
1.4z + 2.2 > 2.6z - 0.2
add 0.2 to both sides
1.4z + 2.4 > 2.6z
subtract 1.4z from both sides
2.4 > 1.2z
divide by 1.2
2 > z
