Answer:
The solution in the attached figure
Step-by-step explanation:
we have

we know that
The solution of the inequality is the shaded area below the dashed line of the parabola
The equation of the dashed line is the vertical parabola 
therefore
The solution in the attached figure
This equation would not be correct.
In the left expression, cscAsecA contains the variable 'e' which is not present in the second expression.
Given:
551.88 + 341.64b
The coefficient of "B" is 341.64, the best statement that applies to it is:
<span>D. It is the cost for one cable box with DVR and HD service for one year.
</span>Cable boxes: $ 3.49 per cable box
HD Service: $ 9.99 per cable box
<span>DVR: <u> $ 14.99 per cable box</u>
</span>Total : $ 28.47
multiply <u> 12 months</u>
Annual cost $341.64
