Matrices

A matrix is a collection of values arranged in rows and columns. Any specific element of a matrix B can be referred to as , where i is the number of the row and j is the number of the column the object is placed in.

Some examples of values given in the matrix of the question are

We are required to calculate:

B_{2,4}-B_{3,2}=9-6=3

Select the second option

john got lost so he didn't know what to do and it was crazy because he didn't except it

step-by-step explanation:

123123 step byt step

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
