 Question 174590: I need help with this problem please. I need to solve and graph the equation. [x] + 2[y] = 7 Thank you so much. Click here to see answer by Mathtut(3670)

 Question 174687: I need to graph this absolute value function: t(x) = 3- the absolute value x.(I don't have the symbol for asb value on my computer) Can you show me how to get the graph points for t(x) or "y"? I know that I have to select random values for "x" like -3, -2, -1, 0, 1, 2, 3, and know the basic rule for solving. But all sample questions that I have seen involve Y = Asb v of x - 3 (or + a number). I really need to figure this out when we are given 3 - asb v "x".
