please help correct the wrong answers thank you!

Put each equation in standard exponential form. (a) y = 2(4-x) 2 y = 4- X (b) y = 9-x/2 y= .9 X (c) Y = XXX X (d) y = 1 - 1\\3+ x/2 10 / X y = 1 3 + X (e) y= 3 0.5452x - 7 0.0828 y = 0.5452x (round values to four decimal places) X (f) y = 3(0.0004567)-0.4x + 2 0.0000006 y = (0.0004567 ) 0.4x (round values to seven decimal places) XIn 1989, research scientists published a model for predicting the cumulative number of AIDS cases reported in the United States: 3 5(1') = 155(%) , (thousands) where t is the year. This paper was considered a "relief," since there was a fear the correct model would be of exponential type. Use the two data points predicted by the research model a(t) for the years 1986 and 1998 to construct a new exponential model b(t) for the number of cumulative AIDS cases. (Round values to three decimal places.) )(t_ 1980) , (thousands) X bu) = 644.322( 1.3160714 Discuss how the two models differ and explain the use of the word "relief." relief is used because the presented numbers are cumulative mat grow fast when the exponential function is used
