An executive invests $26,000, some at 8% and some at 6% annual interest. If he receives an annual return of $1,860, how much is

S_A_V [24]

Let x = amount invested at 8%
26000 - x = amount invested at 6%

0.08x + 0.06(26000 - x) = 1860

solving the equation you get x = 15000
and subtract that from 26000 you get 11000
8% investment = 15000
6% investment = 11000

If y=5x - 2 were changed to y=3/4 x- 2, how would the graph of the new function compare with the first one?

Andre45 [30]

Hi there! The answer is B. it would be less steep.

The change of the function (in this case) influences the slope of the line. Since we've modified the slope from 5 to 3 / 4, the line will be less steep.
