Answer:
4y^(2)+14y+31
Step-by-step explanation:
First you need to do (y+7)(y+7)
y^2+7y+7y+49
y^2+14y+49
Add it all together
y^2+14y+49+3y^2-15
4y^(2)+14y+31
Answer:
<h2> C</h2>
<h2>Translation Definition</h2>
Translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized.
The rust-colored item is the pre-image, and the blue item is the image.
In a translation, every point of the object must be moved in the same direction and for the same distance.
When you are performing a translation, the initial object is called the pre-image, and the object after the translation is called the image. So, in the picture above, the rust-colored item is the pre-image, and the blue item is the image. We know this because the arrow tells us the direction in which the image was moved. For other images, you might be told which image is the pre-image, or you might be asked to find either the pre-image from the image, or vice versa. It is C because it is moved to a different spot and not reflected.
Answer:
im too dumn
Step-by-step explanation: (1x-21)
Answer:
(6x-2) - (-x+5)
= 6x-2 +x -5
= 7x -7
if you're trying to solve for x, then look below
7x=7
x=1
Your answer is in the picture above
