the value of a baseball card in dollars has been found to be 0.15y+0.35, where y is the number of years since it was released. by how much is the baseballs cards value increasing per year.
To determine how much the baseball card's value is increasing per year, we need to find the derivative of the given equation, which represents the rate of change or the slope of the line.
The given equation is: V = 0.15y + 0.35
Taking the derivative of V with respect to y, we get:
dV/dy = 0.15
Therefore, the baseball card's value is increasing by 0.15 dollars per year.
