Which equation represents a circle that contains the point (-2, 8) and has a center at (4,0)? Distance formula: voy - +03 - ?
(x - 4)2 + y = 100
(x - 4)2 + y = 10
+ (y - 4) = 10
x+(-4)* = 100

Marcus and cody both leave the park at the same time, but in opposite directions. if cody travels 6 mph faster than marcus and after 4 hours they are 64 miles apart, how fast is each traveling? solve using rare times time = distance.

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola is (0, –12). the y-intercept of the second parabola is (0, –24). what is the positive difference between the a values for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth
