Answer:
Step-by-step explanation:
As the equation is x+y=8 , dividing each term by 8 , we get. x8+y8=1. and hence, intercepts formed by the line on x -axis is 8 and on y -axis too it is 8 . Hence mark the intercepts 8 on each axis and join them to draw the graph of x+y=8
The function of f(x) is 20 for the middle problem idk the others
2:3 I think
1. 6/15, 0.4, 40%
2. 0.15, 15%
3. 18 green marbles
