At noise pollution cellular, plan a is $30.00 per month and $5.00 for every gigabyte of data. plan b is $50.00 per month and $2.00 for every gigabyte of data used. irfan wants to find out which plan is the best choice for him. on average, he uses five to eight gb of data per month. write an equation for each plan with monthly data, d, and total cost, c.

Suppose you want to transform the graph of the function y=tan(x+pi/4)-1 into the graph of the function y=-tan(x+pi/2)+1 which transformations should you perform. a) reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up. b) reflect the graph of the first function across the x-axis, translate it pi/4 units to the right, and translate it 2 units up. c) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the left, and translate it 2 units up. d) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the right, and translate it 2 units up.
