Evaluate each expression for x=3, y= -4 and z= 6.

-y- x

-z + y - x

example from our teacher- evaluate each expression for a=-4 and b= -5
-a - (-b) <
) - (-5) <
) <
4+5=9

so i am wondering if for the questions if you do the (double negative) like a thing where it then becomes the opposite.

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)
