Lines a and b are represented by the equations given below: line a: x + 2y = 3 line b: x + y = 3 which statement is true about the solution to the set of equations? (1 point) there are infinitely many solutions. there are two solutions. there is one solution. there is no solution.

answer: procent 54 wynosi 33,33%

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
