Question

If b is the midpoint of line ac and Ac is 8x-20 find bc

Answer 1

Line BC = 4x - 10

Step-by-step explanation:

The midpoint will always be halfway between the two points. For this example, line AB and line BC must be equal to each other since point B intersects halfway. Since the whole line, or line AC, is 8x - 20 units, halving this gives 4x - 10 units.

Do your proof by adding both together:

(4x - 10) + (4x - 10)

Add like terms:

8x - 20!
