Suppose you have 3 quizzes and want an average of 7 points. list at-least 5 ways this average can be achieved. each score can be no higher than 10 points.

You can start from the trivial case: you get 7 points per quiz. So, your marks are 7, 7, 7 and the average is obviously 7.

From here, you can build as many examples as you like: we need a total score of 21 distributed among the three quizzes: for example, you can choose

4, 9, 8, since 4+9+8=21, or

6, 7, 8, since 6+7+8=21

and so on.

alright well the answers to your question is

2xy/9 hope this have a nice day : )

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
