3.) Give an example of 2 numbers that have a sum of o. Using words and/or a visual model, justify your answer. How do you know these two numbers have a sum of 0

Use the elimination method to solve the system of equations -x+5y=-4 and 4x+3y=16

Alake near the arctic circle is covered by a 222-meter-thick sheet of ice during the cold winter months. when spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. after 333 weeks, the sheet is only 1.251.251, point, 25 meters thick. let s(t)s(t)s, left parenthesis, t, right parenthesis denote the ice sheet's thickness sss (measured in meters) as a function of time ttt (measured in weeks).

For what value of (y) is 3^3/3^y =1/9
