Answer:
0
Step-by-step explanation:
First, you plug -9 into g(x) and you get g(-9) = - 1. After that, you solve f(-1), which you then reach the solution of 0 by solving.
Let Sam be (S+8) years while his sister is S years.
S(S+8) = 105
S^2+8S-105 = 0
(S+15)(S-7) = 0
Sam’s sister is 7 years and Sam is 15 years old.
1. Common ratio is 5
2. 47
3. I believe the answer is -18, though you might want a second opinion on it to make sure it's correct.
Hope this helped! Good luck! :)
Answer: the commission received by the salesperson is $576.9225
Step-by-step explanation:
Let x represent the auction price
At the dealership, a sales person sold the boat for 30% more than the auction price. It means that the amount for which he sold the boat is
x + (30/100 × x)
= x + 0.3x = 1.3x
If the dealer paid $10,000 for a boat at an auction, it means that
1.3x = 10000
x = 10000/1.3
x = 7692.31
The difference between the auction price and the dealer price is
10000 - 7692.31 =$2307.69
The sales person received a commission of 25% of the difference between the auction price and the dealer price. It means that the commission received by the salesperson is
25/100 × 2307.69 = $576.9225
