On a math quiz, you earn 10 points for each question answered correctly. In the equation below. x represents the number of questions that you answer correctly on this quiz, and y represents the total number of points you score on this quiz. The relationship between
these two variables is modeled by the equation y - 10x.

A)The value of 10 in the equation

B)The total number of points scored of the exam

C) The number of questions answered correctly on the exam

D)The independent variable cannot be determined from the given information

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

i believe the correct answer is b.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
