This year, the girl scouts sold 2 more than four times as boxes of cookies as they did last year. This year they sold 402 boxes. How many boxes did they sell last year? Please hurry!

An equation of the line tangent to y=x^3+3x^2+2 at its point of inflection is

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) .

Solve for the equation. 4x - 13 = 2x + 9
