The expression 1.08s + 1.02b1.08s+1.02b predicts the end-of-year value of a financial portfolio where ss is the value of stocks
Marysya12 [62]

Answer:

$22350 is the predicted value of portfolio.

Step-by-step explanation:

The given expression is 1.08s + 1.02b1.08s + 1.02b which predicts the end of year value of a financial portfolio.Here s = value of stocks and b = value of bonds.

Now we have to calculate the value of a portfolio with s = $200 and b = $100

So we will put the values of s and b in the given expression to calculate the value portfolio.

1.08×200 +1.02×(100)×1.08×(200)+ 1.02×(100) = 216 + 22032 + 102

= $22350

The predicted end to end year value of portfolio is = $22350

If a line contains both point s and the origin, which point would the line also contain?
Ne4ueva [31]
The answer is y = 2x + 0 or y = 2x.

The line passes through (0,0) and (1,2). The slope is

m = (2 − 0)/(1 − 0) = 2.

(You could also see this by drawing the two points and a slope triangle and use the rise/run idea of slope.)

In the slope-intercept form, y = mx + b, you now know that m = 2 and b = 0, so the answer is

y = 2x + 0 or y = 2x.
