Answer:
f(-1) = -4
Step-by-step explanation:
f(-1) simply means that what is f(x) when x = -1?
Just plug in -1 for <em>x</em> to find your answer:
f(-1) = -3(-1) + 2(-1) - 5
f(-1) = 3 - 2 - 5
f(-1) = 1 - 5
f(-1) = -4

Answer:
the total price of the CD, including tax is $14.31
Step-by-step explanation:
The computation of the total price of the CD including tax is shown below:
= Sale price - off percentage + sales tax
= $15 - ($15 × 10%) + 6% of the remaining value
= 15 - $1.5 + 6% of the remaining value
= $13.50 + 6% of $13.50
= $13.50 + $0.81
= $14.31
Hence, the total price of the CD, including tax is $14.31

Answer:
The value after three years is $137,027.97
Step-by-step explanation:
Here, we want to get the value of the home after 3 years
Generally, we have the exponential formula as follows;
y = P(1 + r)^t
where P is the original cost which is $124,400
r is the rate of increase which is 3% = 3/100 = 0.03
t is the time which is 3 years
Substituting these values;
y = 125400(1 + 0.03)^3 = $137,027.97
