Describe the pattern in the table using an equation. explain how you did it .

y = 10x + 5

The difference in the consecutive values of y is 10

That is 25 - 15 = 10 , 35 - 25 = 10 , 45 - 35 = 10

multiply the corresponding value of x by the difference and note what has to be added or subtracted from it to give y

x = 1 ⇒ y = (10 × 1 ) + ? = 15

x = 2 ⇒ y = (10 × 2 ) + ? = 25

x = 3 ⇒ y = (10 × 3 ) + ? = 35

x = 4 ⇒ y = (10 × 4 ) + ? = 45

In each case ? = 5

The required equation is y = 10x + 5

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

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
