One safe investment pays 10% per year, and a more risky investment pays 13% per year. a. How much must be invested in each account if an investor of $100,000 would like a return of $10,870 per year?
b. Why might the investor use two accounts rather than put all the money in the 13% investment?

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

0 is its x and y coordinate

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
