Answer:
D
Step-by-step explanation:
A translation would be shifting the figure in any direction, but the figure would retain it's shape and pqrs would all be at their same corners. A reflection means the figure will essentially be "flipped" across an axis, and in this case it would be the y-axis as you can imagine "folding" over the y-axis and having the figures line up.

Answer:
9x+4
Step-by-step explanation:
Answer:
A and D
Step-by-step explanation:
Given
x² - 10x - 5 = 9 ( add 5 to both sides )
x² - 10x = 14
To compete the square
add (half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = 14 + 25
(x - 5)² = 39 ← take the square root of both sides
x - 5 = ± ( add 5 to both sides )
x = 5 ±
Hence
x = 5 - → A
x = 5 + → D
