Bis the midpoint of a . if ab = x+5 and bc =2x-11, find the measure of ab

If B is the midpoint of AC, then AB = BC.

We have AB = x + 5 and BC = 2x - 11.

Therefore we have the equation:

x + 5 = 2x - 11       subtract 5 from both sides

x = 2x - 16       subtract 2x from both sides

-x = -16      change the signs

x = 16

Put the value of x to the expression x + 5:

AB = 16 + 5 = 21

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
