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:
W(x) = 0.126x + 76.74
M(x) = 0.169x + 69.11
where W(x) represents the life expectancy for women and M(x) represents the life expectancy for men, and x represents
the number of years since 1975. (x = 0 corresponds to the year 1975, x = 5 corresponds to the year 1980 and so on.)
Write an inequality that represents in what years the life expectancy of men is greater than that of women.
a 0.169x + 69.11 > 0.126x+ 76.74
b. 0.169x + 69.11 <0.126x + 76.74
C. 0.169x + 69.11 < 0.126x + 76.74
d. 0.169x + 69.11 = 0.126x + 76.74
