If y = (x - 3)^2 what is the value of y when x = 4?

Twice the sum of a number and 4 is equal to three times the difference of the number and 7. find the number.

Divide. reduce the answer to lowest terms.5 2/3 ÷ 3 1/9

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.
