25. Two rectangular plots of land are equal in area. The length of the first plot is one and a half
times its width. The length of the second plot is
7 metres less than three times its width
(a) Denoting the width of the first plot by
x metres and the width of the second plot
by y metres, derive a relation between
and y.
(b) If y = x + 1, calculate the values of
x and y.​

Simply 8x squared + 5(7x squared- x) - 2x =

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.
