There are two types of plants in a greenhouse. The following dot plots show the heights of 20 plants, 10 of Type 1 and 10 of Type 2. The plants are given the same amount of food and water and grow at the same rate. What is the mean height for each type of plant? Make a comparative inference based on the mean values. Use pencil and paper. Explain why you would want to use a dot plot to find the mean instead of a box plot. the mean height .PEARSON

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.
