Answer:
a = - 4, b = 5
Step-by-step explanation:
Expand the left side, then compare the coefficients of like terms.
- 3(2x² + ax + b)
= - 6x² - 3ax - 3b, compare to - 6x² + 12x - 15
Compare coefficients of x- terms
- 3a = 12 ( divide both sides by - 3 )
a = - 4
Compare constant terms
- 3b = - 15 ( divide both sides by - 3 )
b = 5
Answer:
The answer is 21 remainder 6
Step-by-step explanation:
Using the Instant-runoff method, it can be inferred that the winner is the tacos because after the first vote, they get 3 more votes that allow them to have more than half of the possible votes (option B).
<h3>What is the instant-runoff method?</h3>
Instant-runnof is a voting method whereby a single winner is selected from a wide variety of options. This method is characterized by allowing voters to choose different options on a scale of first option, second option, third option.
According to the above, in the first vote the sandwiches are eliminated because they had the lowest vote (3 votes). Then, a new vote must be carried out with the products that were left that were Pizza and Tacos.
On the second ballot, tacos get 3 more votes because voters who voted for Sandwich on the first ballot had Tacos as their second choice. So the bottom line is Pizza with 9 votes and Tacos with 11 votes.
In short, the Tacos win by having more than half of the possible votes 11/20.
