Maria walks a round trip of 0.75 mile to school every day.how many miles will she walk in 4.5 days

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
