30 points. participant a runs at a slower rate than participant b. both participants run at a constant rate. this table represents participant a. time (min) 5 8 12 15 number of laps run 2.75 4.4 6.6 8.25 which equation could represent participant b? time in minutes is represented by x and number of laps run is represented by y. select each correct answer. y = 0.3x y = 0.9x y = 0.7x y = 0.5x

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)

Drag each expression to the correct location on the solution. not all expressions will be used. consider the polynomial 8x + 2x2 - 20x - 5. factor by grouping to write the polynomial in factored form.
