mestny [16]3 years ago
3 0

Answer:

Step-by-step explanation:

Adding the two equations together gives you

9x-10y-9x-6y=145+15

-16y=160

y=-10, using this value in 9x-10y=145 gives you

9x-10(-10)=145

9x+100=145

9x=45

x=5

So y=-10 and x=5

What is the rate of return on a $12,500 bond purchased at $10,750 with a 15% coupon?
Firdavs [7]
With the 15% coupon, you will get $1,875. (Because 15% of the bond's price $12,500 is $1,875.) Solution: 0.15 x 12500 = 1875

So $1,875 is to be divided by the actual price of the bond which is $10,750. (1, 875 ÷<span>  10,750 = 0.1744 convert this to percent to get the rate of return)
 0.1744 = 17.44 %

The rate of return is 17.44%.</span>

Can someone help please?
Marina CMI [18]

Answer:

  g(7) = 16

Step-by-step explanation:

When evaluating piecewise-defined functions, the first step is to determine which domain the value of the independent variable falls into. Then the associated function is evaluated in the usual way.

__

For x=7, the applicable domain is (2, ∞). This means the applicable function is ...

  g(x) = (x +1)(x -5)

For x=7, this is ...

  g(7) = (7 +1)(7 -5) = (8)(2)

  g(7) = 16
