Write the augmented matrix for each system of equations. 1 0 0 0 9/4
0 1 0 0 3/5
0 0 1 0 2/3
0 0 0 1 -9/5

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

yep b and c r the correct got it! : )
