Equation of a parabola with vertex at (2, -1) is
y = a(x - 2)^2 - 1
Using the given point: -3 = a(4 - 2)^2 - 1
-2 = a(2)^2
4a = -2
a = -1/2
Therefore, required equation is
y = -1/2(x - 2)^2 - 1
y = -1/2(x^2 - 4x + 4) - 1
y = -1/2x^2 + 2x - 2 - 1
y = -1/2x^2 + 2x - 3

whattt do I have to do translate what???
Answer:
C.
Step-by-step explanation:
The equation for the slope of a line is y2-y1/x2-x1, and both triangles have the same slope equation for their hypotenuse.
Answer:
3
Step-by-step explanation:
Square: 4 equal sides
If x is one of the sides:
Perimeter: 4x
12: 4x
x=3
