draw a number line sketch to check your solutions ...
B, C, and E are three points on a line such that B - E - C. The coordinate of E is - 7 and the coordinate of C is greater than that of coordinated of B. if BC = 19 and CE = 8, find the coordinates of B and C. (use algebraic method)
BE + EC = BC
BE + 8 = 19
BE = 19 - 8 = 11
Solve: for coordinate B.
|B - E| = 11
|B - (-17) | = 11
- (B - (-7)) = 11
B + 7 = - 11
B = - 11 - 7
B = - 18....
i am in finding coordinate of C. because | C - E | = 8 then C - (-7) = 8 and C + 7 = 8 will C = 8 - 7 = 1... is this correct sir?
thanks
