Answer:
36-54i
Step-by-step explanation:
(9+9i)(-1-5i)
v
-9-9×5i-9i-9i×5i
v
-9-45i-9i-45i^2
v
-9-45i-9i-45×(-1)
v
(-9)-45i-9i+(45)
v
36(-45i)(-9i)
v
36-54i
Answer:
(-1, 4)
Step-by-step explanation:
In the figure attached,
Ordered pair representing point P is (3, 4) [parallel to y-axis]
If this point has been reflected across a line x = 1
New point after reflection across x = 1 will be,
P(3, 4) → P'(-1, 4)
Since point P and P' will be equidistant from the line (x = 1), so the x ordinate of P' will be = 3 - 4 = -1
And y-ordinates of point P' will be same as y = 4
Answer:
D
Step-by-step explanation:
Translating a shape is basically moving it across the grid. By translating 2 units left and 1 unit up, you'll be moving point C 2 squares to the left, giving you (0, -5). And by translating 1 unit (or square) upwards, will give you the coordinates of (0, -4).
F^2=h-2g
f=√h-2g
