Which equation has only one solution?
|x – 5| = –1
|–6 – 2x| = 8
|5x + 10| = 10
|–6x + 3| = 0

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
