Geometry:(

*image shown above*

Which of the following equations is of the parabola whose vertex is at (2, 3), axis of symmetry parallel to the y-axis and p = 4? a.)y-3 = 1/16 (x-2)^2 b.)y+3 = -1/16 (x+2)^2 c.)x-2 = 1/16 (y-3)^2

X2 + y 2 = 36 x + y = 6 solve the system of equations.

Write the expression as a single natural logarithm. 2 in a - 4 in y
