B) The sum of three numbers is 348. The second number is twice as big as the first and the third number is 12 more than the first. What are the three numbers?

X+y=-4 x-y=2 use elimination with adding and subtraction

In which direction does the left side of the graph of this function point? a(x) = 3x - x2 + 4x - 2

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part 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 (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
