Express 64 1/2 in simplest radical form

What is the equation of a line passing through the point (6,1) and parallel to the line whose equation 3x=2y+4

To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1

When x = 3 and y = 5, by how much does the value of 3x2 – 2y exceed the value of 2x2 – 3y ?
