Answer:
– 21x^3 y – 9x^2 y^2 e) is your answer
Step-by-step explanation:
Solve the following system for A and B:
{A = 7 x^2 + 3 x y
B = -3 x y
Express the system in matrix form:
(1 | 0
0 | 1)(A
B) = (7 x^2 + 3 x y
-3 x y)
Write the system in augmented matrix form and use Gaussian elimination:
(1 | 0 | 7 x^2 + 3 x y
0 | 1 | -3 x y)
Collect results:
Answer: {A = 7 x^2 + 3 x y , B = -3 x y
then we multiply the results (7 x^2 + 3 x y) ( -3 x y) = – 21x^3 y – 9x^2 y^2

Solution: We are given:
Predicted Sales by Sameera ![=38](https://tex.z-dn.net/?f=%3D38)
Actual Sales by Sameera ![=28](https://tex.z-dn.net/?f=%3D28)
Now to find the Percent error, we have to use the below formula:
![=\frac{|38-28|}{28} \times 100 \%](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%7C38-28%7C%7D%7B28%7D%20%5Ctimes%20100%20%5C%25)
![=\frac{10}{28}\times 100 \%](https://tex.z-dn.net/?f=%3D%5Cfrac%7B10%7D%7B28%7D%5Ctimes%20100%20%5C%25)
![=35.71 \%](https://tex.z-dn.net/?f=%3D35.71%20%5C%25)
Therefore, the percent error is
The first image has a coordinate of A'(1, 6) B'(-3, 7)
<h3>How to calculate the coordinates of an image after a translation?</h3>
Translation can be defined as movement in a straight line.
Given the rule: (x,y) → (x + 3, y - 1) and A(-2,7) B(-6,8)
That means: A(x = -2, y =7) B(x = -6, y = 8)
Thus the translation will be:
A'(-2 +3, 7-1) B'(-6+3, 8-1) = A'(1, 6) B'(-3, 7)
Therefore, the coordinate of the image is A'(1, 6) B'(-3, 7)
