An equation for the depreciation of a car is given by y=A(1-r)^t, where y= current value of the car, A=original cost, r=rate depreciation, t=time, in years. The value of a car is half what it originally cost. The rate of depreciation is 10%.Approximately how old is the car?

Which number produces a rationale number when multiplied by 1/5

What is the equation of the line in point-slope form? y+ 4 = 1/2(x+4) y-4 = 1/2(x + 4) y-0 = 2(x - 4) y-4 = 2(8-0)
