Sally has only nickels and dimes in her money box. she knows that she has less than $20 in the box. let x represent the number of nickels in the box and y represent the number of dimes in the box. which of the following statements best describes the steps to graph the solution to the inequality in x and y? draw a dashed line to represent the graph of 5x + 10y = 2000, and shade the portion above the line for positive values of x and y. draw a dashed line to represent the graph of 10x + 5y = 2000, and shade the portion above the line for positive values of x and y. draw a dashed line to represent the graph of 5x + 10y = 2000, and shade the portion below the line for positive values of x and y. draw a dashed line to represent the graph of 10x − 5y = 2000, and shade the portion below the line for positive values of x and y.
