Last year, the school library had a total of x books. over the summer, the library acquired another 35 books and now has a total of 2,943 books. which equation could be used to find x, the number of books the library had last year?

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29

Someone me what is the area of this figure? 18m 18m 8m 16m

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.
