Answers by Angel P.

You can get the vertex form by completing the square. this is currently in standard form (ax2 + bx + c) In f(x) = x2-4x+9, b = -4 We need to get (b/2)2 to complete the square.  b = -4 (b/2)2 = (-4/2)2 = (-2)2 = 4 Now we take this number and add it to both...

14y+4x=-14 (answer)

To simplify this problem, let's try to solve for Y so we can just input values for X. 14y + 4x = -14 14y = -14 - 4x                     Move 4x to the other side of the equation 14y = -14 - 4x           ...
