A) y = 5(x + 2)² + 9
C) y = 3(x − 2)? + 9
B) y = 17(x – 2) – 9
D) y = 48(x - 2)² – 9

$18 was the price of the t-shirt

step-by-step explanation:

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

y = i/2 xtnop + (3i/2 tnop+ 1)
