Question 12 1 pts
Which system of equations requires the most work before solving it by applying the
elimination method?
O [x-12y = -2
[x+8y=-3
O [x+12y = 3
(12y - 9x = 6
None of the other answers are correct
O [9x - 12y = -6
1-2x-12y = 3
O (3x + 12y = 9
1-2x-6y=-21

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

answer: 0.64
