​ ​The car wash owner uses the equation
y
=
x
+
44
y=x+44 to model the data, where
x
x represents the number of days the business has been open and
y
y represents the number of cars washed.
​Which explanation best describes whether the equation is a good fit for the data?

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

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
