Answer:

1. (3x² - 7x + 14) + (5x² + 4x -6) = B

2. (2x² - 5x - 3) + (-10x² + 2x + 7) = A

3. (12x² - 2x - 13) + (-4x² + 5x + 9) = C

Step-by-step explanation:

(3x² - 7x + 14) + (5x² + 4x -6)    (We can simplify this since there are like terms)

= 8x² - 3x + 8    (This is denoted in option B so the answer to the first question is B)

(2x² - 5x - 3) + (-10x² + 2x + 7)    (We can simplify this since there are like terms)

= -8x² - 3x + 4    (This is denoted in option A so the answer to the second question is A)

(12x² - 2x - 13) + (-4x² + 5x + 9)    (We can simplify this since there are like terms)

= 8x² + 3x - 4    (This is denoted in option C so the answer to the third question is C)

Answer:

(x + 13, y + 7)

Step-by-step explanation:

Hello there!

In order to find what the translation rule is, we need to find how much it move to the right/left and up/down

In this case, the line segment VW moved up 7 and to the right by 13

We can get this by checking how far apart the points are

I checked how far apart V and V prime

(V prime is the green V. When a point is primed, its just saying that the point has gone through translation, rotation, dilation, or reflection)

V is 13 units to the left of V prime and 7 units below V prime

This means that, to go from line VW to line V prime W prime, you need to shift the line up 7 units and to the right 13 units

So, the translation rule is (x + 13, y + 7)

*If you don't understand, tell me in the comments, I will try to explain further to your understanding. Thank you, and have a great rest of your day :)*
