Using the equation y=9x you can substitute x for the hours. Y=9 times 5 and y=9 times 8. Y=45 and y=72. The range is $45-$72
Answer: 47 and 16
Step-by-step explanation:
- Make Two Equations
x + y = 63
x - y = 31
- Set one of the equations equal to one of the variables
x + y = 63
x = 31 + y
- Substitute the equation back into the other one
(31 + y) + y = 63
31 + 2y = 63
2y = 32
y = 16
- Substitute the answer back into the equation
x + y = 63
x + 16 = 63
x = 47
Answer:
-x^2 +9x -2
Step-by-step explanation:
f(x) = – x^2 + 6x - 1 and g(x) = 3x
- 1,
(f + g)(x) = f(x) + g(x)
= – x^2 + 6x - 1 + 3x
- 1
Combine like terms
= -x^2 +9x -2
Answer:
$354,600
Step-by-step explanation:
The PV (present value) of a USD 100,000 outcome at the end of each year for the next four (4) years is USD 354,600.
Present value (PV) of annuity = USD 100,000 at 5% for 4 years
Present Value of Annuity of $1
= 3.546 × USD 100,000
= $354,600
