Somebody please help me Indicate whether the lines are parallel, perpendicular, or neither. Justify your answer. y=52x-3 and 2y= -5x -4 2x+8y= -24and 48y = -12x-144 2x-7y= -56and 7x+2y=8

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400

What is the value of x in the following equation. -x ^3/2 = -27

Simplify. (-2)^-3 a. -8 b. -1/8 c. 1/8 d. 8
