Rita and Tina each make $11 an hour working as cashiers at a supermarket. Last week, Rita worked rhours while Tina worked thours. Rita also
worked overtime hours during the week, for which she was paid an extra $32 flat wage. Which expressions represent the total weekly wages of
both Rita and Tina?

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: 5100 just subtract

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
