In 1989, research scientists published a model for predicting the cumulative number of aids cases reported in the united states: a(t) = 155 t − 1980 10 3 , (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 1985 and 1995 to construct a new exponential model b(t) for the number of cumulative aids cases. (round values to three decimal places.) b(t) = incorrect: your answer is incorrect.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
