We'll have to assume that these triangles are similar.
If that's the case, then the following ratio is true:

38 55
------- = --------
15.2 x

Then 38x = 836, and x = 836/38 = 22 (answer)

Please help me. if you can help me answer multiple questions only 3. offering 30 points for it

Answer:

(-9, -5)

Step-by-step explanation:

Ok, so when you move an image to the right, you are moving along the x-axis, and when you move up, you are moving up the y-axis. So if the altered image is (x,y) and the values are (-5, -1), you reverse what has been done to the image. In this case, since we moved to the right 4 units, we know that means we added 4 to x, so we subtract 4 to get -9. And then, for the y-value, because we added 4, we do the opposite, and subtract 4 to get -5. So the pre-image should be (-9, -5)
