We can do 'point' arithmetic.

M = (A+B)/2

2M = A+B

B = 2M - A

We have M(3, -4) and A(8, -5)

B = 2(3, -4) - (8, -5) = (6,-8) - (8,-5) = (-2, -3)

Check:

(A+B)/2 = ( (8+-2)/2, (-5+ -3)/2) = (3, -4) good

Answer: (-2, -3)

12*10^5 or 1.2*10^6 which one is closer to 1 million? please explain.

Salsk061 [2.6K]

12*10^5 = 12*100000 = 1200000 ;
1200000 - 1000000 = 200000 ;
1.2*10^6 = 1.2*1000000 = 1200000;
1200000 - 1000000 = 200000;
Because 2000000 = 200000, neither of the two numbers is closer to 1 milion !
