📝 Answered - Life expectancy in the U.S. is steadily increasing due to medical advancements and the increased awareness of maintaining a healthy lifestyle. The life expectancies for men and women in the U.S. can be modeled by the following functions: [tex] \begin{array}{l} W(x)=0.126 x+76.74 \\ M(x)=0.169 x+69.11 \end{array} [/tex] where [tex]$W(x)$[/tex] represents the life expectancy for women and [tex]$M(x)$[/tex] represents the life expectancy for men, and [tex]$x$[/tex] represents the number of years since 1975. ([tex]$x=0$[/tex] corresponds to the year 1975, [tex]$x=5$[/tex] corresponds to the year 1980 and so on.) Write an inequality to determine the birth years of women whose life expectancy is at least 85. A. [tex]$0.126 x+76.74 \leq 85$[/tex] B. [tex]$0.126 x+76.74 \geq 85$[/tex] C. [tex]$0.126 x+76.74\ \textless \ 85$[/tex] D. [tex]$0.126 x+76.74=85$[/tex]
