Answer:

Step-by-step explanation:
the first - is for reflection
-2 is for translating right (its essentially)
+9 is for translation up
lmk if you want be to explain more
In general, the intersection of two planes is the line passing through the points shared by the plane.
In this case, it would be line RW.
Answer:
D ( x -2i sqrt(2)) ( x+ 2i sqrt(2))
Step-by-step explanation:
x^2 + 8
We want to factor so rewrite as squares
x^2 + (2sqrt(2))^2
Rewrite with a subtraction sign i^2 = -1
x^2 - (2*i*sqrt(2))^2
This is the difference of squares
a^2 - b^2 = ( a-b) (a+b)
( x -2i sqrt(2)) ( x+ 2i sqrt(2))
Answer:
y = -2x + 7/6
Step-by-step explanation:
y-2/3=-2(x-1/4)
Distribute the -2
y-2/3=-2x+ 2/4
y - 2/3 = -2x + 1/2
Add 2/3 to each side
y - 2/3 + 2/3 = -2x + 1/2 + 2/3
Get a common denominator
y = -2x + 3/6 + 4/6
y = -2x + 7/6
