50 points an unknown number x is at most 20. which graph best represents all the values of x? (1 point) number line graph with closed circle on 20 and shading to the right. number line graph with open circle on 20 and shading to the right number line graph with closed circle on 20 and shading to the left. number line graph with open circle on 20 and shading to the left

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.
