Please help! Correct answer only, please! I need to finish this assignment this week. Determine the value of the following: A. B. C. D.

Option B is correct

Step-by-step explanation:

To subtract matrix A from matrix B which has the same size as matrix A, you find the pair corresponding elements (which share the same position in matrix) and perform the subtraction.

As shown in picture:

C = A - B

   = [3-(-1)  2-0; -4-(-5)  6-2; 7-4  5-9]

   = [4 2; 1 4; 3 -4]

=> Option B is correct

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
