Is (7, 8) a solution to the equation y = x?
Yes or No?

no

Step-by-step explanation:

y=x

Substitute the point into the equation

8=7

This is not a true statement, so the point is not a solution

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

miss u!

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
