h - length of the hypotenuse
Use the Pyhagorean theorem:

This is my way of doing it...
Rearrange the equation to -x^2+4x+3
Then -(x^2 - 4x) + 3
-[(x-2)^2 - 4] +3
-[(x-2)^2] +4+3
-(x-2)^2 + 7
final answer : y=7-(x-2)^2
Answer:
g = -2/3
Step-by-step explanation:
-g + 6 +2g = -4g - (-4)
g + 6 = -4g + 4
3g =-2
g = -2/3
I hope this helps you
100-y=x^2.
x= square root of 100-y
y^-1= square root of 100-x
