So your equation is 2x^{2} +7x = 4. You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now 4x + 7x = 4.
You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's 11x = 4 right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be

0.36.

I hope I helped!

Geometry PEOPLE HELP
White raven [17]

Answer: second option.

Step-by-step explanation:

Given the transformation T:(x,y)→(x-5,y+3)

 You must substitute the x-coordinate of the point A (which is x=2) and the y-coordinate of the point A (which is y=-1) into (x-5,y+3) to find the x-coordinate and the y-coordinate of the image of the point A.

Therefore, you get that the image of A(2,-1) is the following:

(x-5,y+3)=(2-5,-1+3)=(-3,2)

You can observe that this matches with the second option.
