Lets assume it is the function in the form: f (x,y)= ax + by +c, a line in three dimensions. Considering given information, we have: f(3,4)=11 --> 3a +4b +c = 11 f(8,12)=63 --> 8a +12b +c = 63 f(9,6)=64 --> 9a+ 6b +c = 64 f(12,10)=? Solving first 3 equations we find a= 18; b= - 55/2 ; c= 67 => f(x,y) = 18x - (55/2) y +67, then f(10, 12)= 180 - 330 +67 = - 83
(12-8)-(6-3)=1 (4-3)-(1-1)=1 (9-6)-(6-4)=1 (12-10)-(4-3)=1
Easy way (4 , 3 ,11 ) 4-3 =1 [11] =1-1=0 1-0 ={ 1}☑️
( 8 , 12 , 63 ) 12-8 =4 [63] =6-3=3 4 - 3 ={1}☑️
( 9 ,6 , 64 ) 9-6 =3 [64] =6-4=2 3-2={1}☑️
Choose the option which is suitable on this condition ( 12 , 10 , ?) We assume
If 2 3 = 10 7 2 = 63 6 5 = 66 8 4 = 96 then 9 7 = ?
IF 1,3,3=5 9,7,4=8 11,14,10=15 20,16,12=18 Than 3,6,7=?
