Answer:
y = -x - 1 & y = -3x - 1
Step-by-step explanation:
(3-4i)(5+6i)
15+18i-20i-24i^2
15+18i-20i+24=
39-2i
3/8 is the right answer to that question
Answer:
(-6, 0).
Step-by-step explanation:
x^2 + 36y^2 + 12x = 0
Convert to standard form:
(x + 6)^2 - 36 +36y^2 = 0
(x + 6)^2 + 36y^2 = 36
Divide through by 36:
(x + 6)^2 / 36 + (y - 0)^2/ 36 = 1
Now compare this with the general form:
(x - h)^2/a^2 + (y - k)^2/ b^2 = 1
We see that the center (h, k) = (-6, 0).
