Think about the volume of the stack. By definition, what is the volume of the stack equal to? Express you answer in words instead of numbers.

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

Find the maximum value of p= 4x + 5y subject to the following constraints :

If the tip varies directly with the number of guest which equation represents between the tip,t, and the number of guest,g?
