Answer:
Bob could predict a <u>100%</u>, as if he has studied for a long time, and has learnt the content, he should be able to get 100%!
Answer:
The Y value part of the point's coordinates will always stay the same, and then calculate the distance from the point's x value to the line -2 and then count the same amount in the opposite direction. For example, if the point was (-3,1), then the point is 1 left from the line, so you will go point one right from the line and get the answer (-1,1)

Answer:
![x^2 +2x-3](https://tex.z-dn.net/?f=x%5E2%20%2B2x-3)
Step-by-step explanation:
Given
![(x - 2)\² + 6x - 7](https://tex.z-dn.net/?f=%28x%20-%202%29%5C%C2%B2%20%2B%206x%20-%207)
Required
The equivalent
We have:
![(x - 2)\² + 6x - 7](https://tex.z-dn.net/?f=%28x%20-%202%29%5C%C2%B2%20%2B%206x%20-%207)
Expand
![(x - 2)\² + 6x - 7 = x^2 -2x-2x +4 +6x - 7](https://tex.z-dn.net/?f=%28x%20-%202%29%5C%C2%B2%20%2B%206x%20-%207%20%3D%20x%5E2%20-2x-2x%20%2B4%20%2B6x%20-%207)
Collect like terms
![(x - 2)\² + 6x - 7 = x^2 -2x-2x+6x +4 - 7](https://tex.z-dn.net/?f=%28x%20-%202%29%5C%C2%B2%20%2B%206x%20-%207%20%3D%20x%5E2%20-2x-2x%2B6x%20%2B4%20%20-%207)
![(x - 2)\² + 6x - 7 = x^2 +2x-3](https://tex.z-dn.net/?f=%28x%20-%202%29%5C%C2%B2%20%2B%206x%20-%207%20%3D%20x%5E2%20%2B2x-3)
Hence, the equivalent is:
![x^2 +2x-3](https://tex.z-dn.net/?f=x%5E2%20%2B2x-3)
