The price of a particular stock is plotted against time in a graph. if the overall shape of the graph has a negative slope, would you invest your money in this stock? explain why or why not.

No, we will not invest money in this stock.

Step-by-step explanation: In the attached figure , the price p of the stock  (Y-axis) is plotted against time t (X-axis). Let P(a,b) and Q(c,d) be any two points on the graph. Since the slope m is negative, so, we have

Since , so, we must have

This implies that, as the time increases, the price of the stock decreases. Hence, it will be a loss investing money in this stock.

Thus, we will not invest money in the stock because there will be loss.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
