10. The value of a copy machine decreases at a constant rate from the time it is sold. It can be modeled by the equation V(t) = -3t- it + 18 where t is the time in years and V (t) is in thousands of dollars. (a) Graph the equation V(t) = -,t+ 18. Label two points on the graph and label the axes so that it corresponds to the variables in the equation. 10 10 (b) State the meaning of V(t) in the context of this problem? Be precise. (c) State the coordinates of the V(t)-intercept. Explain the meaning of the V(t)- intercept in the context of this problem. (d) State the coordinates of the t-intercept. Explain the meaning of the t-intercept in the context of this problem. CIT
