I'm very confused how to do this. could you help me?

(a) graph 2

(b) graph 3

(c) graph 1

Step-by-step explanation:

if the grades on the y line/side (idk) are very high (ex: 400 on graph 1) then that means the person could've gotten up to that and with the amount of time on the x line/side. if the grades are normal and so are the time limits (graph 2) then that's neautral. if there is a crazy amount of study time with just an average grade then that shows studying a lot did not increase the grades.

r and t.

both are 64 degrees.

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.
