(4x2y3 + 2xy2 – 2y) – (–7x2y3 + 6xy2 – 2y)

11x²y³ - 4xy²

Step-by-step explanation:

Distribute the first parenthesis by 1 and the second by - 1

Given

(4x²y³ + 2xy² - 2y) - (-7x²y³ +6xy² - 2y)

= 4x²y³ + 2xy² - 2y + 7x²y³ - 6xy² + 2y ← collect like terms

= (4x²y³ + 7x²y³) + (2xy² - 6xy²) + (- 2y + 2y)

= 11x²y³ + (- 4xy²) + 0

= 11x²y³ - 4xy²

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)
