Answer:
-48x^2 -666x+84
Step-by-step explanation:
Exponet is ^2.
Multiply is •
Use Distributed Property. Multiply the second parathesis by each term from the first parathesis.
Any expression multiplied by 1 remains the same. Distribute 41 through the parathesis. 41(2-7x-9x).
Distribute 3x through the parathesis 3x • (2-7x-9x).
You will have these numbers left: (Slide 2)
Add the numbers, 2 and 82 to get 84. Add -7x -9x + -287x -369x + 6x to get -666x. Add -21x^2 - 27x^2 to get 48x^2.
Use the communitative property to reorder the terms. And then your answer is -48x^2 -666x+84.

Answer:
![y = x - 4](https://tex.z-dn.net/?f=y%20%3D%20x%20-%204)
Step-by-step explanation:
Given
-- correct expression
Required
Represent as slope intercept form
![2y - 2x = -8](https://tex.z-dn.net/?f=2y%20-%202x%20%3D%20-8)
Make 2y the subject
![2y = 2x - 8](https://tex.z-dn.net/?f=2y%20%3D%202x%20-%208)
Divide through by 2
![\frac{2y}{2} = \frac{2x}{2} - \frac{8}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2y%7D%7B2%7D%20%3D%20%5Cfrac%7B2x%7D%7B2%7D%20-%20%5Cfrac%7B8%7D%7B2%7D)
![y = x - 4](https://tex.z-dn.net/?f=y%20%3D%20x%20-%204)
