Find two different sets of parametric equations for the given rectangular equation (there are many correct solutions) 13) y= x^2+10 14) x+y^2=4 15) x^2 + 4y^2 - 16 = 0

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

What is the value of the expression below? 148+(-6)| + |– 35= 7|

On #16 : explain how factoring a trinomial, ax^2+ bx+ c, when a does not equal 1 different from factoring a trinomial when a = 1.
