What are the coordinates of point d?
(graph up top )

(a.) (4, -2)

(b.) (-2, -4)

(c.) (4, -1.5)

(d.) (4, -2,5)

C

Step-by-step explanation:

From the graph, you see that the point D

is ( x=4, y=-1.5 )

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

answer: i guess 105 degrees?
