Answer:
D
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x² - 4 - (x + 2) ← distribute parenthesis by - 1
= 3x² - 4 - x - 2 ← collect like terms
= 3x² - x - 6
Answer:
Step-by-step explanation:
Let x be the number of miles Jan can drive in a taxi.
The cost of this ride consists of
- $5.00 flat rate
- $.065 per mile
So, per x miles Jan will pay $0.65x and the total cost of the ride will be
$5.00+$0.65x
Jan has no more than $20 to spend on a ride, then the total cost of his ride must be less or equal to $20. Mathematically, you can write this as
Answer:
f(1) = -4
Step-by-step explanation:
Given that,
f(x) = 2x-6
We need to find the value of f(1).
Put x = 1 in the above expression.
f(1) = 2(1)-6
= 2-6
= -4
So, the value of f(1) is equal to -4.
Answer:
76800
Step-by-step explanation:
Current subscriber=4800
After 3 years=2*4800=9600
After 6 years=2*9600=19200
After 9 years=2*19200=38400
After 12 years=2*38400=76800
