Someone help quick I don’t know if I’m right on the question

About 6 cents per minute

Step-by-step explanation:

Looking at the actual minutes and cost of the plan you can see this. Let's start with the first minutes given (100 with $14) which then goes to 200 with $20. There is a difference of 100 between the two and a difference of 6 with 14 and 20. If you would do 100*0.06 (6 cents) then you would see that for every 100 minutes there would be $6 being paid, in which is the difference between all the bottom numbers when going from left to right.

A more algebraic way to do this is by finding the slope from points we can make from the table (for example 100,14 , 200,20 , 300,26...). now let;s find the slope in which the two points (100,14) and (200,20) share. Using the slope formula we substitute in our values so that the new equation would look like which when adding like terms makes it or in this case 0.06. The slope would be 0.06 and therefore every minute that is on the phone, $0.06 will be added to the bill.

where's the diagrams?

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
