PLS HELP ASAP i don’t understand the question and i cant leave this test to go look at the answer

y-8

Step-by-step explanation:

y-8

Step-by-step explanation:

1) Use coordinates

C (-1, 3) C' (5, -5)     3-(-5)=8     The triangle is translated down so you write y - 8

2) Count from the line that C is on to C'

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
