There are 15 plates in a kitchen cabinet. The diameter of each plate is either 7 inches or 12 inches. The diameter of all 15 plates combined is 140 inches. Which system of equations can be used to find the number of 7-inch plates, x , and the number of 12-inch plates, y , that are in the cabinet?

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?
