A) reflection of P across the x-axis is at (3, 4).
Step-by-step explanation:
The relevant transformations are ...
(x, y) ⇒ (x, -y) . . . . . . reflection across the x-axis
(x, y) ⇒ (-x, y) . . . . . . reflection across the y-axis
__
A) sign of y-coordinate has changed: reflection across the x-axis
B) signs of both coordinates have changed: reflection across both axes
C) sign of x-coordinate has changed: reflection across the y-axis
D) sign of y-coordinate has changed: reflection across the x-axis
The only answer choice that has a proper description is Choice A.
Answer:
d=7
Step-by-step explanation:
An=A1+(n-1)d
32=11+(4-1)d
32=11+3d
-11+32=3d
21=3d
d=7

Answer:
Step-by-step explanation:
Given that EF ║ AB.
So, we have: 
Also, 
Note that: AC = CE + EA = 3 + 4 = 7 and CE = 3
Therefore, 
Hence, the answer.
