Determine which property of determinants the equation illustrates. 4 5 4 5 2 -6 4 -4 6 -4 4 4 3 5 if one row of a matrix is a multiple of another row, then the determinant of the matrix is zero. if one row of a matrix consists entirely of zeros, then the determinant of the matrix is zero. if two columns of a matrix are interchanged, then the determinant of the matrix changes sign. if a row of a matrix is multiplied by a scalar, then the determinant of the matrix is multiplied by that scalar. none of these ic n n

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
