Answer:
If a student with 2 absences got a score of 12, we can affirm that the student got 6 points for every absence she or he had.
Therefore, if a student had 3 absences and the results varied inversely with the number of absences they had, it means that her or his score would be: 3 * 6 = 18 points.
<u>The correct answer is 18 points.</u>
Step-by-step explanation:
The first is proportional the second is proportional and the third is not proportional
Step-by-step explanation:
x = 3 and y = 5.
1: 2xy
2 x 3 x 5
=30
2: 6y divided by x
6 x 5 / 3
30/3
=10
3:4y- x
4 x 5 -3
20-3
=17
4:Y(to the power of two) -7x +2
5^2 -7 x 3 + 2
25-7x3+2
25-21+2
25-19
=6
