it took 3 weeks to thin by 0.75m, so that's 0.25m/wk
y = 2 - 0.25x
I need help pls!
1. A lake near the Artic Circle is covered by a 2-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 3 weeks, the sheet is only 1.25 meters thick.
Let y represent the ice sheet's thickness (in meters) after x weeks.
Complete the equation for the relationship between the thickness and number of weeks.
y=
