Nicole makes $9.50 per hour working at an electronics company. she plans to buy a hand-held computer, the least expensive of which costs $245.60 and the most expensive of which costs $368.40. write and solve an inequality describing how long nicole will have to work to be able to buy a hand-held computer.
give me steps on how to solve this problem. you.

Which of the following points is collinear with (-2,1) and (0,3)

The center of a circle represent by the equation (x+9)^2+(y-6)^2=10^2 (-9,6), (-6,9), (6,-9) ,(9,-6)

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) .
