You can put this solution on YOUR website! |x - 6| =
Ans: x = 6

Find an equation for the line with the given properties. Express the answer using the slope-intercept form of the equation of a line.
Slope = 0; containing the point (-8, -1)
Ans: y = 0x - 1
-------------------------
Find the real solutions of the equation by factoring.
x^2 - 49 = 0
Factor:
(x-7)(x+7) = 0
x = 7 or x = -7
-------------------------------
Write the expression in the standard form a + bi.
(4 + 8i)(2 - 5i)
= 4(2-5i) + 8i(2-5i)
---
= 8-20i+16i-40i^2
-----
= (8+40) + (16-20)i
-----
= 48 - 4i
-----------------
Find the center (h, k) and radius r of the circle.
x2 + (y + 4)2 = 36
----
(x-0)^2 + (y-(-4))^2 = 36
----
h = 0 ; k = -4 ; r = sqrt(36) = 6
