Answer:
(x-y)(x-y)(x-y)(x-y)
Step-by-step explanation:
(x-y)^4 means multiply (x-y) four times
Answer:
(4x -2y)-( 2x-6y) = 2x-(-4y)
Step-by-step explanation:
only the same sign can be together. so you take the x first 4-2 which is 2x then you take the y signs 2-6 which would be -4 the full equation becomes 2x-(-4)
Answer:
Parallel
Step-by-step explanation:
Answer:
(x+4)^2 + (y+3)^2 = 5^2
Step-by-step explanation:
The equation of a circle is
(x-h)^2 + (y-k)^2 = r^2
now substitute the known values
(x+4)^2 + (y+3)^2 = 5^2
and theres your equation
