Reflect the triangle over the y-axis and find the coordinate of the image of point k.

Okay, all you have to do is reflect the triangle over the y-axis by finding each of the points distance from the y-axis. For example. If one of your coordinates was (3,2) you would reflect it over to (-3,2). Can you give me point K's coordinates?

Step-by-step explanation:

K’(2, 1)

Step-by-step explanation:

because its right

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
