Andre is paid $4 per hour for the first 30 hours he works every week. he makes $5 per hour for each hour he works over 30 hours per week. in other words, total wages = fixed wages for 30 hours + additional wages at $5 per hour. write a function that gives andrew's total wages when he works more than 30 hours.

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) .

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab
