Aline segment on a number line has it's endpoints at -9 and 6 . find the coordinate of the midpoint of the segment. selection is 1.5, -1.5, 2, or -3

-1.5

Step-by-step explanation:

The middle of a line segment is its midpoint. To find the midpoint of a line segment, you just calculate the averages of the coordinates.

If a line segment on a number line has its endpoints at -9 and 6, then the coordinate of midpoint is

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
