Half of the product of two consecutive numbers is 105. Which equation can be used to solve for n, the smaller of the two numbers? n2 n â€" 210 = 0 n2 n â€" 105 = 0 2n2 2n 210 = 0 2n2 2n 105 = 0.

Consider the reflection of parallelogram pqrs across the line of reflection, . if rr' = 14, then rz = . if sx = 5, then = 5.

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) .

The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year
