Justin is considering two websites for downloading music. the costs are detailed here:
website 1: a yearly fee of $30 and $1.50 for each download
website 2: $2 for each download.
what is a system of equations to represent the costs for one year? express your equations in the form of y=mx+b where x is the number of downloads for the year and y is the total cost for the year.

, me! i am so confused on this one! !

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
