Tamara has decided to start saving money for spending money for her first year of college. Her money is currently in a large suitcase under her bed, modeled by the function s(x)=450. She is able to babysit to earn extra money and that function would be a(x))=6x-2, where x is measured in hours. Explain to Tamar how she can create a function that combines the two, and describe any simplification that can be done

Part a : solve -vp + 40 < 65 for v part b : solve 7w - 3r = 15 for r show your work .

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
