a lake near the arctic 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 s represent the ice sheet's thickness (in meters) after t weeks.
complete the equation for the relationship between the thickness and number of weeks.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
