Yes
Explanation:
2x9=18 and 1+8=9
The pattern repeats
Slope= y^2-y^1
————
x^2-x^1
slope= 12-0
——-
6+2
slope= 12
—-
8
slope= 3/2
perpendicular slope is the opposite reciprocal
perpendicular slope= -2/3
Answer:
7 wrong answers.
Step-by-step explanation:
We know that when you answer a question well, you earn 8 points and a bad one loses 5 points, this means that when you answer 1 good and 1 bad, there is a total of 3 points (8-5).
This means that when answering 5 good and 5 bad, in total it would be 3 * 5 points, that is to say 15 points, that is, it goes through 2 points. To subtract 2 points, you would have to answer 1 good and 2 bad, (8 - 2 * 5), which turns out to be -2 points.
In total there would be 6 questions right and 7 questions wrong, like this:
8 * 6 + 5 * 7 = 13
13 points, in 13 questions (6 correct + 7 incorrect)
The rest of the questions were not answered so that the score does not go up or down.
Which means you got 7 wrong answers.
The answer to your question is 40.5 units.
