A citizen wants to propose to the city council extending the hours at the local public library on some weekdays. To measure support for extended hours, the citizen visits neighborhood homes and asks adults the following: "Would
you agree that the closing time of the library should be extended by one hour on weekdays to accommodate
working families? Of the 212 adults surveyed, 86% agreed with the statement. Which of the following statements
about the results is true?
O The 86% support provides substantial evidence that the library hours should be extended.
More families should be asked the same question to be sure of community support.
The survey suffers from question wording bias and may not represent true support for the extended hours.
The survey suffers from voluntary response bias and may not estimate true support for the extended hours.

The 86% support provides substantial evidence that the library hours should be extended

step-by-step explanation:

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.
