Answer:

- 8

Step-by-step explanation:

To evaluate f(8) substitute x = 8 into f(x)

f(8) = - 2(8) + 9 = - 16 + 9 = - 7

Similarly for g(- 1)

g(- 1) = (- 1)² - 2 = 1 - 2 = - 1

Then

f(8) + g(- 1) = - 7 + (- 1) = - 7 - 1 = - 8

On March 20, 2011, a $1,000 bond had a selling price of $987.50. What was the quoted price for the bond?
Leviafan [203]

Answer:

98.75%.

Step-by-step explanation:

On March 20, 2011, a $1000 bond had a selling price of $987.50.

We are asked what will be the quoted price for the bond.

Now, the quoted price of a bond is the price at which the bond was last traded and it is expressed as the percentage of the original bond value.

So, in our case the quoted price will be \frac{987.50}{1000} \times 100 = 98.75 %. (Answer)

Define a variable, write an equation, and solve.
allochka39001 [22]

Answer:

  • c(m) = 39.95 +0.35m
  • 85 minutes over 500

Step-by-step explanation:

Let m represent the number of minutes used over 500. Then the cost of the cell phone plan is ...

  c(m) = 39.95 +0.35m

__

For a cost of 69.70, the number of excess minutes can be found by solving ...

  69.70 = 39.95 +0.35m

  29.75 = 0.35m . . . . . . . . . subtract 39.95

  29.75/0.35 = m = 85 . . . . divide by the coefficient of m

The number of minutes of usage over 500 is 85.
