Jeramy's algebra notes from a recent class were chewed up by the family dog. He found the scrap pictured below: S-2x + 3y = 18
23x - 3
Jeramy remembers that when the class graphed the system of equations, the two lines intersected at the point (6, 10).
Write an equation beginning with "3x –" that fits the situation as Jeremy remembers it.
Explain how you found your answer.

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).

Which is a true statement about an exterior angle of a triangle a. it is formed by two segments that are not sides of the triangle, b. it forms a linear pair with one of the interior angles of the triangle, c. it is complementary to one of the interior angles of the triangle. d. it is formed by two segments that are sides of the triangle.

Which equation results from adding the equations in this system? x+6y=9 and -x+2y=-15
